These radar systems are increasingly exploiting active electronically scanned array (AESA) technology to dynamically interleaved functions. However, the increasing complexity and adaptive nature of MFR radar makes it very difficult to specify their performance in a way which can both deliver the required capability and which can be verified in a cost-effective manner. Addressing the challenges in this area will benefit via better understood requirements which can be more easily interpreted. After definition of FoM (Figures of Merit) for phased array radar operation and performance, we have computed them on benchmark test scenarios of varying complexity. We describe a new methodology to aggregate these metrics to provide a global notation of MFR radar performances.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"16 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":"130385186","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}

Such systems are based on simultaneous analysis of the Doppler shift caused by aircraft moving with respect to multiple radio signal sources and network of receivers. One of the aspects of the technique is extraction of Doppler signatures from within spectrogram, for which a robust technique was developed and tested with a variety of different weather and terrain conditions and antenna configurations. The system was able to trace 73% of observed Doppler signatures. Among testing sessions one particular situation in which aircraft is beyond the visible horizon or over-thehorizon (OTH) was analysed with respect to capability of aircraft tracking with the transmitting-receiving network. Such radar system is designed as combination of peer to peer and server side protocols for exchanging information on Doppler shift and aircraft location, respectively. The multistatic configuration of the radar system is built out of three receiving and three transmitting stations located in south east part of Finland and adjoined part of Russian Federation. The efficiency and precision of the tracking system was estimated to OTH visibility and equaled 420km and 1500m, respectively. The precision of the tracking system was verified with reference data based on Automatic dependent surveillance - broadcast (ADS-B) information.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"1 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":"133744507","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 Frequency non-linearities of FMCW SAR seriously deteriorate its range resolution. To overcome this problem and integrate the non-linearity correction method into the imaging algorithm, in this paper, we propose a non-linear range-Doppler algorithm for FMCW SAR. For practical application, the non-linearity error is truncated by neglecting the high-order terms, and the feasibility of this approximation is demonstrated. The Doppler shift induced by the continuous motion is also considered in the proposed algorithm. Finally, the efficiency of the proposed algorithm is verified with simulated FMCW SAR data.","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":"116625961","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}

First of all, WSA parameters such as waveguide dimensions, slot length, slot width, slot displacement and other parameters of the antenna are calculated by using analytic techniques for 25 GHz. After, in order to suppress side lobe level Taylor and Chebyshev coefficients are determined in detailed and then we calculate slot displacements for each slot. The antennas are simulated according to Taylor and Chebyshev coefficient to obtain low side lobes and also reach effective result, which have high efficiency, high gain and small size, for 25 GHz. Sixteen and thirty-six slots are used to obtain desired results like high gain and narrow beam width at the H-plane. According to simulation results, the antennas which have sixteen and thirty-six slots presents 15.9 and 19.3 dBi realized gains, −17.2 and −16.1 dB side lobe levels (SLL), 9.6 and 4.1 deg. half power beam widths at 25 GHz, respectively. The most significant part of this paper is that change of antenna polarization. Normally longitudinal slots have linear polarization and to obtain circular polarization inclined or cross slot are used. However, these slot structure require complex analytic approach and optimization of the structure takes a lot of time. So, effective approach to change antenna polarization are presented.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"37 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":"134147674","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}
