However, the estimated radial velocity of moving target can be ambiguous due to the interferometric phases are almost wrapped by the traditional two-antenna ATI method. In the paper, we propose a two-antenna SAR/ATI method with multiple carrier frequencies for radial velocity ambiguity mitigation of moving targets. Firstly, we establish the model of a two-antenna SAR system and analyze the basic principle of the multi-carrier-frequency ATI (MCF_ATI) approach. Then, we apply the model and the approach to process real SAR data embedded with a simulated moving target, the results demonstrated the effectiveness of the MCF_ATI approach.","PeriodicalId":346680,"journal":{"name":"2016 17th International Radar Symposium (IRS)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127218566","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}

This occurs when the correlation sidelobes of a strong target echo masks weaker echoes. In order to overcome this limitation, the sounding signals which have correlation functions with suppressed sidelobes may be used. When designing such signals, the power efficiency should be considered, which is increased by decreasing the peak to average power ratio of the waveform. In this paper filter-based waveform design methods are presented and discussed. Three different approaches are analyzed that modify filter-based sidelobe suppression algorithms in order to achieve good power efficiency of the output waveform. Both simulation and measurement results are shown presenting, the benefits of the proposed methods.","PeriodicalId":346680,"journal":{"name":"2016 17th International Radar Symposium (IRS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128040957","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}

Managing radar information is currently a task of separate radar systems or integrated navigational systems. However ICT systems used on board and in marine environment have become more and more sophisticated and navigational radar on board is definitely a part of them. The idea presented in this paper is to use object modelling techniques, known from ICT and GIS, for modelling of radar information on board of the ship. Radar information is presented in the form of UML class diagram and the model itself takes into account many aspect of radar information management like raster images, tracked targets, trial maneuver or integration with AIS.","PeriodicalId":346680,"journal":{"name":"2016 17th International Radar Symposium (IRS)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126054196","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 radar measurements were carried out with the highly versatile MEMPHIS radar operating in sea configuration at X, Ka and W band simultaneously. Concerning the oceanographic and atmospheric characterization, the WTD 71 was responsible for the collection of measurements with a sophisticated suite of sensors partly mounted on the research vessel Elisabeth Mann Borgese. Over a period of four days a valuable dataset was collected including clutter measurements under different geometrical configurations. In this contribution the focus is given to the propagation aspects where dedicated propagation runs were carried out each day. First measurement results will be presented and an insight in the overall approach will be given together with a modelling approach based on the parabolic wave equation with input parameters from the meteorological and oceanographic sensors.","PeriodicalId":346680,"journal":{"name":"2016 17th International Radar Symposium (IRS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127465659","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}
