Over-the-air deramping is a technique for wirelessly synchronising distributed passive FMCW radar nodes to a dual-frequency master FMCW transmitter node. Such a system allows simultaneous monostatic and multistatic measurements for improved clutter resilience, and multiple looks at a target for reduced susceptibility to signal fading due to target scintillation. To prove the latter, a simultaneous monostatic and OTAD bistatic node were set up with a 5 m baseline and a walking person was measured. The results show that signal fading occurs in both the monostatic and the bistatic node, but rarely at the same time. Hence, combining the measurements from the two nodes gives a consistent response from the target. This demonstrates OTAD as a compelling system for a robust perimeter surveillance system.","PeriodicalId":267194,"journal":{"name":"2015 IEEE Radar Conference","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128008660","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 Constant False Alarm Rate (CFAR) algorithms, different detectors can be implemented like linear, square law or Bessel detectors. These detectors have difference detection performances and computational costs. In this paper, the detection performances of these three detectors are investigated for CA-CFAR and Order Statistic CFAR (OS-CFAR) algorithms using simulated and measured data of semi-urban desert terrain. Monte Carlo simulation was used to compute the performance in both Gaussian noise and Weibull interference. Results obtained using both simulated and measured data show that the square law detector offers superior performance to the linear and Bessel detector for the OS-CFAR algorithm. In the case of the CA-CFAR algorithm, the square law detector offers the best performance for large values of the Weibull shape parameter. When the Weibull shape parameter is small, the linear detector offers the best performance.","PeriodicalId":267194,"journal":{"name":"2015 IEEE Radar Conference","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126733181","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 solve this issue, firstly, this paper analyzes system demands on the computational capability, the storage capacity and the I/O bandwidth. Then, the method that the real time signal processor and data storage system are integrated on one board is presented. A combination structure with a monolithic FPGA, a monolithic DSP, and CF card is presented to realize the function of the real-time signal processing and the data storage. Three approaches relative to the computational capability, I/O bandwidth and storage capacity are presented to meet the requirements of miniature SAR in this paper. In addition, for the issue of the abnormal response time in the data writing of the CF card, the data buffer of radar data during the response time is realized by the multiplexing of DDR3 SDRAM. Finally the function and performance of the integrated system are tested on the experimental Ku band FMCW SAR. The results show that the integrated system generates the imaging data with the range swath of 800 m in real time and stores the SAR data with the fastest rate over 100MB/s. In addition, the system has the weight of 700 gram, the power consumption less than 16 W.","PeriodicalId":267194,"journal":{"name":"2015 IEEE Radar Conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116616538","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 model enables the average expected estimation error and temporal resource loading to be calculated for varying operational parameters.

The performance model is used to demonstrate the benefit of additional nodes in a radar network as well as the influence of the radars to target geometry on the estimation error. The necessity of a resource management mechanism that effectively balances the allocation of the network resources is highlighted.","PeriodicalId":267194,"journal":{"name":"2015 IEEE Radar Conference","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116853809","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 four polarization combinations data are correlated for they characterize the same target from a specific aspect angle using different polarization modes. To efficiently utilize the information for recognition performance enhancement, a joint sparse representation (JSR) based method for FPHRRP recognition is presented. Each single-polarization HRRP is represented by the atoms which are adaptively selected from its corresponding dictionary, and these atoms derived from different dictionaries have the same index set. Compared to conventional methods, the proposed method has the significant advantage of exploiting the correlation among single-polarization HRRPs to boost recognition performance. The experiment results show that the proposed method achieves promising recognition accuracy and is robust with respect to noisy observations.","PeriodicalId":267194,"journal":{"name":"2015 IEEE Radar Conference","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126812701","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 synthetic aperture radar imagery, the effect of coherent averaging and motion from the sea will also influence the statistics. The goal of this paper is to examine the effect of image formation on the radar backscatter of the X-band Ingara medium grazing angle data set. A number of recently developed distributions are considered for modelling the amplitude statistics including the K+Rayleigh and Pareto+noise, both of which account for thermal noise.","PeriodicalId":267194,"journal":{"name":"2015 IEEE Radar Conference","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114193083","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}

Many works focused on accurately localizing one or two targets laying within a narrow beam centered around the monopulse antenna boresight direction.

A second set of antennas can be required to localize two targets sharing the same elevation or azimuth angles.
