LVD is a recently developed time-frequency representation method for multicomponent linear frequency modulated (LFM) signal. Therefore, the proposed algorithm has superior performance in multiple moving target imaging scenario. By using LVD to represent the multiple moving targets in Doppler centroid frequency and chirp rate domain, each targets' Doppler parameters can be easily read, and the target velocities in both slant-range and along-track directions can be estimated accurately. Focused target responses for multiple moving targets can be obtained simultaneously by simply matched-filtering or other advanced approaches. Point target simulations are designed and carried out to validate the effectiveness and superiority of the proposed algorithm.","PeriodicalId":117775,"journal":{"name":"2015 16th International Radar Symposium (IRS)","volume":"33 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114050174","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}

Traditionally, people use regular RF and microwave signal generators to stimulate radar warning receivers in order to measure the analog RF performance. Many different test cases allow to validate every single parameter. Yet, once test cases with more realistic signals become necessary for operational testing towards the end of the development cycle, it is quite a complex task to generate meaningful signals to stimulate the receiver in order to fully evaluate its performance. Dedicated test systems are available on the market and are traditionally used for these tasks, but they suffer from several technical drawbacks beyond the cost factor. These systems cannot generate continuous signals together with pulsed signals simultaneously as they normally use a fast hopping synthesizer concept. This paper introduces a novel solution which allows to generate complex RF signals for real world simulation scenarios based on commercially available PC software and vector signal generator hardware.","PeriodicalId":117775,"journal":{"name":"2015 16th International Radar Symposium (IRS)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114566703","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}

These characteristics can be low sidelobe level, narrow beamwidth, high directivity, pattern nulling in special angle and etc. For each of these characteristics, different methods have been introduced. Most of methods have been presented for uniform arrays, however there are lots of methods to obtain a desired pattern for antennas with non-uniform element distances. The problem with these methods is complexity or not very good results. In this paper, fast and easy methods based on Least Square Error that leads to good results are presented. In addition, weighting of thinned arrays as a special case of non-uniform arrays is studied here. Mono-pulse pattern synthesis (most important method of angular positioning) in thinned arrays employing the presented method is the other aim of this paper.

This challenge can be well solved by using high-frequency (HF) ocean radars installed at the coast. These systems are capable to monitor sea surface far beyond the horizon and deliver information about sea state parameters and vessel tracking. Performance of the WERA HF ocean radar systems was analyzed for both oceanographic and vessel tracking applications under adverse meteorological conditions during severe storm Xaver, which crossed the German Bight on December 5-6, 2013. The results showed that radars survived the storm and were providing measurements continuously. The radar coverage was reduced suitably in range during the storm to give adequate measurements of sea surface current velocity. The sailing vessels were identified in strong variable sea clutter caused by wave heights up to 8 meters.","PeriodicalId":117775,"journal":{"name":"2015 16th International Radar Symposium (IRS)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129892873","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 of these rely on radar sensors as a source of information about surrounding objects. Based on this information, for example, emergency braking maneuvers are initiated. This requires a very high reliability of the provided data. In the long term, these requirements will become even stricter as highly automated driving comes into play. In the near future, this will result in a high density of radar sensors operating simultaneously and in close proximity. This constellation generates mutual car-to-car interference if no precautions are taken. At present, efforts in measures to mitigate the interference concentrate on time-frequency signal processing. Spatial filtering using digital beamforming is another powerful method. This paper aims to cover the chain of interference, from the basic principles of waveform interaction in a radar sensor's receiver stage, up to mitigation techniques and consequences for signal processing in the presence of interference.","PeriodicalId":117775,"journal":{"name":"2015 16th International Radar Symposium (IRS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130500423","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}
