The original 0.5 – 10.5 GHz covered frequency range is experimentally demonstrated to broaden to 28.5 GHz, limited by laboratory constraints, and a simulative analysis ensures exceeding the 0.5 – 40 GHz goal by simply employing commercially available electro-optical devices accepting higher RF driving voltages. The receiver upgrade relies on a simple and novel technique that triples the number of lines in the exploited optical comb. Photonic integration of the whole receiver will enable next generation ESM systems with further improved compactness and performance.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124378723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this aim a two-dimensional filter bank is proposed with the generic filter impulse response depending on the target electrical size and on the target trajectory that are a priori unknown. In order to limit the computational load required by the bank for practical applications, a two-step processing is proposed: in the first step a rough estimate of the target cross-baseline velocity component is obtained by applying the Radon transform to the spectrogram of the acquired signal while in the second step the bank is exploited to refine the velocity estimation provided by the previous step and also to provide a rough estimation of the target electrical size. The performance of the proposed approach is analyzed against synthetic data under different case studies such as different motion directions, baseline crossing points and different target dimensions. Finally results obtained by applying the proposed processing to FM-based passive FSR experimental data are shown demonstrating the effectiveness of the considered approach.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124541719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its primary objective, the acquisition and generation of a global Digital Elevation Model (DEM) with 12 m horizontal resolution and 2 m relative height accuracy, has been completed in autumn 2016. Since the end of 2010 the two twin synthetic aperture radar (SAR) satellites TerraSAR-X and TanDEM-X have been flying in a controlled close orbit formation. The resulting large single-pass SAR interferometer allowed to map the complete Earth's land surface at least twice. Moreover, the flexibility offered by both SAR instruments in terms of imaging, interferometric, and polarization modes, has been further exploited to serve several secondary mission objectives, e.g. acquisitions based on along-track interferometry as well as new bistatic SAR techniques. In this paper, we present the current status and activities within the mission and the quality assessment of the final TanDEM-X global DEM.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"530 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114747536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to obtain the best possible detection rate, while minimising false alarms, there is a need to measure and evaluate the performance of a system under development. In the case of vital signs monitoring systems, the target observation time is a very sensitive parameter. The two main unknowns are: when will the incident that we want to detect occur and how long must it be observed for a robust detection to be established. This paper shows a novel approach of so-called dynamic analysis of the detection probability for real or simulated data. This approach helps us to identify the statistical limits of the system and to find an optimum between the minimum observation time window and the maximum detection probability.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117072404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The basic principle of the respiratory motion detection consists in the identification of sensor signal components possessing a significant power in the frequency band 0.1–0.7 Hz (frequency band of human respiratory rate) corresponding to a constant range between the target and radar antennas. However, the problem of person localization associated with the estimation of their breathing rate has not been studied deeply. In order to fill this gap, an approach for a joint localization and breathing rate estimation of persons will be introduced in the paper. For that purpose, a radar signal processing proceure for multiple static person localization along with their breathing frequency estimation will be introduced in this paper. The performance of the proposed procedure will be evaluated for the experimental scenario intent on through-the-wall localization and respiratory rate estimation of two static persons using single UWB radar employing one transmitting and two receiving antennas.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116013159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The algorithm uses a Kalman filter to predict the relative position and speed of the interceptor with respect to the target. The transmitted waveform is automatically selected based on its ambiguity function and accuracy properties along the approaching path. For each pulse, the interceptor predicts its position and velocity with respect to the target, takes a measurement of range and radial velocity and, with the Kalman filter, refines the relative range and range rate estimates. These are fed into a Linear Quadratic Gaussian (LQG) controller that ensures the interceptor reaches the target automatically and successfully with minimum error and with the minimum guidance energy consumption.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117221934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to best exploit the HRWS capabilities as successor of the current Sentinel-1 mission, a study focused on the HRWS applications was recently founded by the European Space Agency. Within this study, a new operational mode, denoted as Beam-Switch Wide Swath (BSWS), was proposed by the German Aerospace Centre to provide a better answer to specific final user needs. In fact, the BSWS exploits the operational flexibility associated with the HRWS multi-channels architecture and digital beamforming capability to generate single/dual-polarimetric (SP/DP) images, interferometrically compatible with the fully polarimetric ones, while keeping the wide coverage of the SP products. This paper presents the BSWS mode, explains its functional principle and analyses its imaging performance, based on a realistic HRWS reference system.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126254474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
