Range-point migration-based image expansion method exploiting fully polarimetric data for UWB short-range radar
Ayumi Yamaryo; Tatsuo Takatori; Shouhei Kidera; Tetsuo Kirimoto
IEEE Transactions on Geoscience and Remote Sensing, Institute of Electrical and Electronics Engineers Inc., 56, 4, 2170-2182, 01 Apr. 2018, Peer-reviwed, Ultrawideband radar with high-range resolution is a promising technology for use in short-range 3-D imaging applications, in which optical cameras are not applicable. One of the most efficient 3-D imaging methods is the range-point migration (RPM) method, which has a definite advantage for the synthetic aperture radar approach in terms of computational burden, high accuracy, and high spatial resolution. However, if an insufficient aperture size or angle is provided, these kinds of methods cannot reconstruct the whole target structure due to the absence of reflection signals from large part of target surface. To expand the 3-D image obtained by RPM, this paper proposes an image expansion method by incorporating the RPM feature and fully polarimetric data-based machine learning approach. Following ellipsoid-based scattering analysis and learning with a neural network, this method expresses the target image as an aggregation of parts of ellipsoids, which significantly expands the original image by the RPM method without sacrificing the reconstruction accuracy. The results of numerical simulation based on 3-D finite-difference time-domain analysis verify the effectiveness of our proposed method, in terms of image-expansion criteria.

INTERNATIONAL JOURNAL OF INFECTIOUS DISEASES, ELSEVIER SCI LTD, 55, ***, 113-117, Feb. 2017, Peer-reviwed, Background: Infrared thermography (IRT) is used to screen febrile passengers at international airports, but it suffers from low sensitivity. This study explored the application of a combined visible and thermal image processing approach that uses a CMOS camera equipped with IRT to remotely sense multiple vital signs and screen patients with suspected infectious diseases.
Methods: An IRT system that produced visible and thermal images was used for image acquisition. The subjects' respiration rates were measured by monitoring temperature changes around the nasal areas on thermal images; facial skin temperatures were measured simultaneously. Facial blood circulation causes tiny color changes in visible facial images that enable the determination of the heart rate. A logistic regression discriminant function predicted the likelihood of infection within 10 s, based on the measured vital signs. Sixteen patients with an influenza-like illness and 22 control subjects participated in a clinical test at a clinic in Fukushima, Japan.
Results: The vital-sign-based IRT screening system had a sensitivity of 87.5% and a negative predictive value of 91.7%; these values are higher than those of conventional fever-based screening approaches.
Conclusions: Multiple vital-sign-based screening efficiently detected patients with suspected infectious diseases. It offers a promising alternative to conventional fever-based screening. (C) 2017 The Author(s). Published by Elsevier Ltd on behalf of International Society for Infectious Diseases.

Three-Dimensional Imaging Method Incorporating Range Points Migration and Doppler Velocity Estimation for UWB Millimeter-Wave Radar
Yuta Sasaki; Fang Shang; Shouhei Kidera; Tetsuo Kirimoto; Kenshi Saho; Toru Sato
IEEE GEOSCIENCE AND REMOTE SENSING LETTERS, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 14, 1, 122-126, Jan. 2017, Peer-reviwed, High-resolution, short-range sensors that can be applied in optically challenging environments (e.g., in the presence of clouds, fog, and/or dark smog) are in high demand. Ultrawideband (UWB) millimeter-wave radars are one of the most promising devices for the above-mentioned applications. For target recognition using sensors, it is necessary to convert observational data into full 3-D images with both time efficiency and high accuracy. For such conversion algorithm, we have already proposed the range points migration (RPM) method. However, in the existence of multiple separated objects, this method suffers from inaccuracy and high computational cost due to dealing with many observed RPs. To address this issue, this letter introduces Doppler-based RPs clustering into the RPM method. The results from numerical simulations, assuming 140-GHz band millimeter radars, show that the addition of Doppler velocity into the RPM method results in more accurate 3-D images with reducing computational costs.

An Objective Screening Method for Major Depressive Disorder Using Logistic Regression Analysis of Heart Rate Variability Data Obtained in a Mental Task Paradigm
Guanghao Sun; Toshikazu Shinba; Tetsuo Kirimoto; Takemi Matsui
FRONTIERS IN PSYCHIATRY, FRONTIERS MEDIA SA, 7, -, 1-7, Nov. 2016, Peer-reviwed, Background and objectives: Heart rate variability (HRV) has been intensively studied as a promising biological marker of major depressive disorder (MDD). Our previous study confirmed that autonomic activity and reactivity in depression revealed by HRV during rest and mental task (MT) conditions can be used as diagnostic measures and in clinical evaluation. In this study, logistic regression analysis (LRA) was utilized for the classification and prediction of MDD based on HRV data obtained in an MT paradigm.
Methods: Power spectral analysis of HRV on R-R intervals before, during, and after an MT (random number generation) was performed in 44 drug-naive patients with MDD and 47 healthy control subjects at Department of Psychiatry in Shizuoka Saiseikai General Hospital. Logit scores of LRA determined by HRV indices and heart rates discriminated patients with MDD from healthy subjects. The high frequency (HF) component of HRV and the ratio of the low frequency (LF) component to the HF component (LF/HF) correspond to parasympathetic and sympathovagal balance, respectively.
Results: The LRA achieved a sensitivity and specificity of 80.0 and 79.0%, respectively, at an optimum cutoff logit score (0.28). Misclassifications occurred only when the logit score was close to the cutoff score. Logit scores also correlated significantly with subjective self-rating depression scale scores (p < 0.05).
Conclusion: HRV indices recorded during a MT may be an objective tool for screening patients with MDD in psychiatric practice. The proposed method appears promising for not only objective and rapid MDD screening but also evaluation of its severity.

Experimental Study on Embedded Object Imaging Method with Range Point Suppression of Creeping Wave for UWB Radars
Toshiki Manaka; Shouhei Kidera; Tetsuo Kirimoto
IEICE TRANSACTIONS ON ELECTRONICS, IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG, E99C, 1, 138-142, Jan. 2016, Peer-reviwed, Ultra-wideband radar exhibits high range resolution, and excellent capability for penetrating dielectric media, especially when using lower frequency microwaves. Thus, it has a great potential for innovative non-destructive testing of aging roads or bridges or for non-invasive medical imaging applications. In this context, we have already proposed an accurate dielectric constant estimation method for a homogeneous dielectric medium, based on a geometrical optics (GO) approximation, where the dielectric boundary points and their normal vectors are directly reproduced using the range point migration (RPM) method. In addition, to compensate for the estimation error incurred by the GO approximation, a waveform compensation scheme employing the finite-difference time domain (FDTD) method was incorporated. This paper shows the experimental validation of this method, where a new approach for suppressing the creeping wave along the dielectric boundary is also introduced. The results from real observation data validate the effectiveness of the proposed method in terms of highly accurate dielectric constant estimation and embedded object boundary reconstruction.

Accuracy Enhanced RPM Method Using Doppler Based Range Points Clustering for 140GHz Band UWB Radar
Shouhei Kidera; Yuta Sasaki; Shang Fang; Tetsuo Kirimoto; Kenshi Saho; Toru Sato
2016 INTERNATIONAL SYMPOSIUM ON ANTENNAS AND PROPAGATION (ISAP), IEEE, *, ***, 628-629, 2016, Peer-reviwed, 140 GHz ultra-wideband millimeter wave radars significantly expand the capacities of three-dimensional (3-D) imaging sensors, making them suitable for short-range surveillance or security purposes. For such applications, we have already developed the range points migration (RPM) method, which achieves highly accurate 3-D boundary extraction. However, to deal with multiple targets with many reflection points, such as a human body, this method suffers from an inaccuracy and an expensive computational cost. As a solution for such difficulty, this paper introduces a Doppler based range points clustering into the RPM method. Results from numerical simulations assuming 140 GHz millimeter radars show that the proposed method achieves more accurate 3-D image associated with Doppler velocity, without sacrificing computational efficiency.

Dielectric Constant and Boundary Extraction Method for Double-Layered Dielectric Object for UWB Radars
Takuya Niimi; Shouhei Kidera; Tetsuo Kirimoto
IEICE TRANSACTIONS ON ELECTRONICS, IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG, E98C, 12, 1134-1142, Dec. 2015, Peer-reviwed, Microwave ultra-wideband (UWB) radar systems are advantageous for their high-range resolution and ability to penetrate dielectric objects. Internal imaging of dielectric objects by UWB radar is a promising nondestructive method of testing aging roads and bridges and a noninvasive technique for human body examination. For these applications, we have already developed an accurate internal imaging approach based on the range points migration (RPM) method, combined with a method that efficiently estimates the dielectric constant. Although this approach accurately extracts the internal boundary, it is applicable only to highly conductive targets immersed in homogeneous dielectric media. It is not suitable for multi-layered dielectric structures such as human tissues or concrete objects. To remedy this limitation, we here propose a novel dielectric constant and boundary extractionmethod for double-layered materials. This new approach, which simply extends the Envelope method to boundary extraction of the inner layer, is evaluated in finite difference time domain (FDTD)-based simulations and laboratory experiments, assuming a double-layered concrete cylinder. These tests demonstrate that our proposed method accurately and simultaneously estimates the dielectric constants of both media and the layer boundaries.

For suitability in such applications, we have already proposed an accurate permittivity estimation method for a 2-dimensional dielectric object of arbitrarily shape and clear boundary. In this method, the propagation path estimation inside the dielectric object is calculated, based on the geometrical optics (GO) approximation, where the dielectric boundary points and its normal vectors are directly reproduced by the range point migration (RPM) method. In addition, to compensate for the estimation error incurred using the GO approximation, a waveform compensation scheme employing the finite-difference time domain (FDTD) method was incorporated, where an initial guess of the relative permittivity and dielectric boundary are employed for data regeneration. This study introduces the 3-dimensional extension of the above permittivity estimation method, aimed at practical uses, where only the transmissive data are effectively extracted, based on quantitative criteria that considers the spatial relationship between antenna locations and the dielectric object position. Results from a numerical simulation verify that our proposed method accomplishes accurate permittivity estimations even for 3-dimensional dielectric medium of wavelength size.

A Robust Signal Recognition Method for Communication System under Time-Varying SNR Environment
Jing-Chao li; Yi-Bing Li; Shouhei Kidera; Tetsuo Kirimoto
IEICE TRANSACTIONS ON INFORMATION AND SYSTEMS, IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG, E96D, 12, 2814-2819, Dec. 2013, Peer-reviwed, As a consequence of recent developments in communications, the parameters of communication signals, such as the modulation parameter values, are becoming unstable because of time-varying SNR under electromagnetic conditions. In general, it is difficult to classify target signals that have time-varying parameters using traditional signal recognition methods. To overcome this problem, this study proposes a novel recognition method that works well even for such time-dependent communication signals. This method is mainly composed of feature extraction and classification processes. In the feature extraction stage, we adopt Shannon entropy and index entropy to obtain the stable features of modulated signals. In the classification stage, the interval gray relation theory is employed as suitable for signals with time-varying parameter spaces. The advantage of our method is that it can deal with time-varying SNR situations, which cannot be handled by existing methods. The results from numerical simulation show that the proposed feature extraction algorithm, based on entropy characteristics in time-varying SNR situations,offers accurate clustering performance, and the classifier, based on interval gray relation theory, can achieve a recognition rate of up to 82.9%, even when the SNR varies from -10 to -6 dB.

Accurate Permittivity Estimation Method with Iterative Waveform Correction for UWB Internal Imaging Radar
Ryunosuke Souma; Shouhei Kidera; Tetsuo Kirimoto
IEICE TRANSACTIONS ON ELECTRONICS, IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG, E96C, 5, 730-737, May 2013, Peer-reviwed, Ultra-wideband (UWB) pulse radar has high range resolution and permeability in a dielectric medium, and has great potential for the non-destructive inspection or early-stage detection of breast cancer. As an accurate and high-resolution imaging method for targets embedded in a dielectric medium, extended range points migration (RPM) has been developed. Although this method offers an accurate internal target image in a homogeneous media, it assumes the permittivity of the dielectric medium is given, which is not practical for general applications. Although there are various permittivity estimation methods, they have essential problems that are not suitable for clear, dielectric boundaries like walls, or is not applicable to an unknown and arbitrary shape of dielectric medium. To overcome the above drawbacks, we newly propose a permittivity estimation method suitable for various shapes of dielectric media with a clear boundary, where the dielectric boundary points and their normal vectors are accurately determined by the original RPM method. In addition, our method iteratively compensates for the scattered waveform deformation using a finite-difference time domain (FDTD) method to enhance the accuracy of the permittivity estimation. Results from a numerical simulation demonstrate that our method achieves accurate permittivity estimation even for a dielectric medium of wavelength size.

Accurate and Nonparametric Imaging Algorithm for Targets Buried in Dielectric Medium for UWB Radars
Ken Akune; Shouhei Kidera; Tetsuo Kirimoto
IEICE TRANSACTIONS ON ELECTRONICS, IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG, E95C, 8, 1389-1398, Aug. 2012, Peer-reviwed, Ultra-wide band (UWB) pulse radar with high range resolution and dielectric permeability is promising as an internal imaging technique for non-destructive testing or breast cancer detection. Various imaging algorithms for buried objects within a dielectric medium have been proposed, such as aperture synthesis, the time reversal approach and the space-time beamforming algorithm. However, these algorithms mostly require a priori knowledge of the dielectric medium boundary in image focusing, and often suffer from inadequate accuracy to identify the detailed structure of buried targets, such as an edge or specular surface owing to employing the waveform focusing scheme. To overcome these difficulties, this paper proposes an accurate and non-parametric (i.e. using an arbitrary shape without target modeling) imaging algorithm for targets buried in a homogeneous dielectric medium by advancing the RPM (Range Points Migration) algorithm to internal imaging issues, which has been demonstrated to provide an accurate image even for complex-shaped objects in free-space measurement. Numerical simulations, including those for two-dimensional (2-D) and three-dimensional (3-D) cases, verify that the proposed algorithm enhances the imaging accuracy by less than 1/10 of the wavelength and significantly reduces the computational cost by specifying boundary extraction compared with the conventional SAR-based algorithm.

Fast and Shadow Region 3-Dimensional Imaging Algorithm With Range Derivative of Doubly Scattered Signals for UWB Radars
Shouhei Kidera; Tetsuo Kirimoto
IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 60, 2, 984-996, Feb. 2012, Peer-reviwed, Ultra-wideband (UWB) radar with its high range resolution and applicability to optically harsh environments, offer great promise for near field sensing systems. It is particularly suitable for robotic or security sensors that must identify a target in low visibility. Some recently developed radar imaging algorithms proactively employ multiple scattered components, which can enhance an imaging range compared to synthesizing a single scattered component. We have already proposed the synthetic aperture radar (SAR) method considering a double scattered, which successfully expanded a reconstructible range of radar imagery with no a priori knowledge of target or surroundings. However, it requires a multiple integration of the received signals, requiring the fifth times integration in the 3-D case. Thus, this method requires an intensive computation and its spatial resolution is insufficient for clear boundary extraction such as edges or specular surfaces. As a substantial solution, this paper proposes a novel shadow region imaging algorithm based on a range derivative of double scattered signals. This new method accomplishes high-speed imaging, including a shadow region without any integration process, and enhances the accuracy with respect to clear boundary extraction. Results from numerical simulations verify that the proposed method remarkably decreases the computation amount compared to that for the conventional method, especially for the 3-D problem, enhancing the visible range of radar imagery.

Accurate and Omnidirectional UWB Radar Imaging Algorithm With RPM Method Extended to Curvilinear Scanning Model
Yoriaki Abe; Shouhei Kidera; Tetsuo Kirimoto
IEEE GEOSCIENCE AND REMOTE SENSING LETTERS, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 9, 1, 144-148, Jan. 2012, Peer-reviwed, Ultrawideband pulse radars are a promising technology for high-quality imaging sensors for rescue robots in the near field because they have the advantage of high range resolution. We have already proposed the accurate and fast imaging algorithm as range point migration (RPM), which employs the direction of arrival (DOA) with the global characteristic of the multiple observed ranges. However, this algorithm assumes the line scanning of an omnidirectional antenna and limits the imaging range. To overcome this limitation, this letter derives an extended RPM method, which accomplishes omnidirectional imaging and accurate target positioning. As a false-image-reduction scheme in this method, this letter introduces a postprocessing algorithm, which constrains the searching range for DOA estimation by using the initial RPM image. The results of numerical simulations, including noisy situations, show that the proposed method accomplishes accurate and omnidirectional imaging on the order of 1/100 wavelength and enhances the imaging range while avoiding false images.

Multi-Static UWB Radar Approach Based on Aperture Synthesis of Double Scattered Waves for Shadow Region Imaging
Shouhei Kidera; Tetsuo Kirimoto
IEICE TRANSACTIONS ON ELECTRONICS, IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG, E94C, 8, 1320-1323, Aug. 2011, Peer-reviwed, The applicability in harsh optical environments, such as dark smog, or strong backlight of ultra-wide band (UWB) pulse radar has a definite advantage over optical ranging techniques. We have already proposed the extended Synthetic Aperture Radar (SAR) algorithm employing double scattered waves, which aimed at enhancing the reconstructible region of the target boundary including shadow region. However, it still suffers from the shadow area for the target that has a sharp inclination or deep concave boundary, because it assumes a mono-static model, whose real aperture size is, in general, small. To resolve this issue, this study proposes an extension algorithm of the double scattered SAR based on a multi-static configuration. While this extension is quite simple, the effectiveness of the proposed method is nontrivial with regard to the expansion of the imaging range. The results from numerical simulations verify that our method significantly enhances the visible range of the target surfaces without a priori knowledge of the target shapes or any preliminary observation of its surroundings.

A new algorithm to generate the reference images of ship targets for ATR using ISAR
K Yamamoto; M Iwamoto; T Kirimoto
IEICE TRANSACTIONS ON COMMUNICATIONS, IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG, E88B, 2, 737-744, Feb. 2005, Peer-reviwed, Inverse synthetic aperture radar (ISAR) is useful for automatic target recognition (ATR) because it can reconstruct a high resolution image of an observed target. In ISAR imaging, 3-dimensional reflectivity distribution of a target is projected to the plane defined by range axis and cross range axis. In order to recognize the observed target by using pattern matching, reference images of candidate targets must be adequately generated. However, that is difficult because the cross range axis, which depends on the target's unknown rotational motion, can not be determined precisely. In this paper, we propose a new algorithm to generate reference ISAR images of ship targets. In this algorithm, tracking data, Doppler width and the slope of the centerline of an ISAR target image are used to specify the cross range axis. The effectiveness of the proposed algorithm was evaluated by using simulated targets.

A MULTIPLE SIDELOBE CANCELER SWITCHING OVER AUXILIARY ANTENNAS ARRANGED IN TRIANGULAR ORDER
T KIRIMOTO; Y HARASAWA; A SHIMADA
IEICE TRANSACTIONS ON COMMUNICATIONS, IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG, E77B, 4, 519-525, Apr. 1994, Peer-reviwed, Many previous works state that a multiple Sidelobe canceller (MSLC) with two auxiliary antennas is successful in suppressing two interference signals received simultaneously by sidelobes of a main antenna. In this paper, we show that the MSLC does not always guarantee such capability in three dimensional applications where the incident direction of interference signals is defined by two angles (elevation and azimuth). We show the singularity of the autocorrelation matrix for the auxiliary channel signals induces the degradation of the capability by analyzing characteristics of MSLC's in three dimensional applications from the view point of the eigenvalue problem. To overcome this singularity, we propose a novel MSLC controlling the placement of auxiliary antennas by means of switching over three antennas arranged triangularly. Some simulations are conducted to show the effectiveness of the proposed MSLC.

IEEE TRANSACTIONS ON INFORMATION THEORY, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 40, 2, 526-532, Mar. 1994, Peer-reviwed, A novel construction is proposed to generate orthogonal periodic sequences whose elements consist of at most q complex numbers which are not expressed in the power of complex primitive roots of unity. The orthogonal periodic sequences are generated by mapping M-sequences on GF(q) into complex periodic sequences.

超広帯域レーダのための偏波及び多重散乱波を用いた画像再現域拡大に関する研究
桐本 哲郎
Principal investigator, 本研究では，災害現場・資源探査等を想定した自律型ロボットの周囲環境把握（目標位置計測・形 状認識等）のための，超広帯域（UWB: Ultra Wideband）電磁波を用いた超分解能画像レーダ技術を開 発する．申請者らは現在まで，超分解能・影領域画像化性能を有する立体イメージングレーダ技術（RPM 法等）を独自に発展させてきた．しかし，室内計測等開口面積が制限される状況では，十分な画像再 現域を確保できず，目標形状認識が困難となる．本研究では，「局所楕円体近似と偏波解析による画像 領域拡大法」と「多重散乱環境を用いた見通し外センシング」を導入し，「散乱周波数特性」・「誘電体 透過性」等の電波固有の性質を積極的に活用した革新的レーダ技術を開発する．更に移動型レーダプ ラットフォームを導入し，災害レスキュー等に近い実験環境による原理検証・性能評価を実施する．
