The conventional thresholding algorithm like constant false alarm rate (CFAR) is noise oriented algorithm which is focused on false alarm. Unlike this algorithm, the proposed algorithm is focused on miss-detection. For some applications miss-detection is more critical than false alarm, especially for short range application like IR-UWB radar sensor, such as anticollision system, intrusion detection. Moreover, the target signal oriented thresholding algorithm may better aware of the environment. As we know the amplitude of the signal varies depending on the installation height and angle of the radar. Conventional noise oriented thresholding algorithm is lack of considering these parameters. However, since the proposed algorithm is a target signal oriented thresholding algorithm, it is automatically optimized for these parameters. We analyzed the thresholds generated by the CFAR based thresholding algorithm and miss-detection probability based thresholding algorithm in the experiment result.","PeriodicalId":436201,"journal":{"name":"2018 19th International Radar Symposium (IRS)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116733490","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}

At least for larger aircraft, a Radar sensor is the key element of such a Sense and Avoid system. The standardization of Sense and Avoid systems is still ongoing and the sensor requirements are still subject to changes. In order to facilitate the validation and verification of requirements as well as to evaluate new Radar modes and algorithms, a flexible and modular demonstrator test bed was designed and realized. On the one hand the test bed makes extensive use of state-of-the art hardware technologies such as System-on-Chip devices and GPUs. On the other hand the use of standard interfaces and MATLAB as a high level programming language enable the rapid prototyping of new functionalities. Comprehensive insight into the hardware and software realization is provided. At the current state the integration of the first flight test configuration is about to be finished.","PeriodicalId":436201,"journal":{"name":"2018 19th International Radar Symposium (IRS)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132806955","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}

At the same time, it is common to partially transfer the pressure of suppressing azimuth ambiguity to range so as to balance antenna size, and thereupon following a problem that the radar echoes in elevation are sensitive to terrain undulation. A promising candidate is the combination of array-fed reflector antenna and Digital Beamforming (DBF) technique. Therefore, this paper establishes an echo model for array-fed reflector antenna and proposes a beamspace based DBF method applied to array-fed reflector antennas. Simulations taking use of the proposed DBF method are carried out to verify the effect on range ambiguity suppression. Aiming at the terrain-undulation-sensitive problem, a derivative constraint to steering vector is added during the DBF process, which greatly improves the robustness of DBF in elevation.","PeriodicalId":436201,"journal":{"name":"2018 19th International Radar Symposium (IRS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130457958","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}

However, drones are particularly difficult to detect with conventional non-cooperative surveillance sensors such as scanning radars as drones have a small RCS and fly low and slow. Here, we use an L-Band staring radar sensor that employs a fully digitized 2-D receiver array to achieve 3-D broad-volume continuous surveillance. The continuity of surveillance allows sufficiently high detection sensitivity to be achieved enabling location of rapidly manoeuvring drones operating in Electro-magnetically congested environments such as airports. Here, we present results from live trials using a staring radar sensor to detect small drones. Detection performance is compared with theoretical predictions.","PeriodicalId":436201,"journal":{"name":"2018 19th International Radar Symposium (IRS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126549756","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 some cases interferometric applications may be limited by specific satellite pointing performance. It will be presented in this paper how the “Frequency Adapter for Interferometric Applications ” (FADI) innovative processing can improve the performance of the final products, with particular emphasis on burst-modes SAR acquisitions. One of the main hypothesis of current processing algorithms is the use of a single processing Doppler centroid, both for focusing and for radiometry equalization i.e. the whitening filter), while FADI technique uses indeed two: two distinct values of Doppler centroid, estimated in each original image, are used for the equalization of the radiometric pattern; on the other hand the same value of Doppler centroid is used for focusing in order to cancel out the term causing decorrelation. Last section of the paper will show how this technique can be applied in particular to burst modes (e.g., Ping-Pong and ScanSAR), offering the possibility to obtain images with correct radiometry and maximum spectral overlap (and thus with maximum coherence).","PeriodicalId":436201,"journal":{"name":"2018 19th International Radar Symposium (IRS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117197531","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}
