The means of the polarimetric processing for reducing the speckle can enhance ability to discriminate targets. Compared with conventional approaches, the subclass features obtained carry more information due to the neural learning and thus make the correctness of target classification higher. The simulation results have verified the validity of this approach.","PeriodicalId":144063,"journal":{"name":"Proceedings of International Radar Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123693018","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}

It also provides dynamic parameters about storms for weather forecasts and identifies thunderstorm hazards by the distribution characteristics of the velocity field, and thus improves the calamitous weather warning and short-term forecasting capability.","PeriodicalId":144063,"journal":{"name":"Proceedings of International Radar Conference","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131780404","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 maximum range detection of the radar is a function of signal/noise (S/N). Because the size of the target is larger than the wavelength of the radar and radar range resolution cells, the backscattered power of the target is recorded as a function of time. The method for improving detection performance with HRR radar is investigated. The performance of the correlation filtering is given. The results show that the method improves the target detection performance with HRR radar.","PeriodicalId":144063,"journal":{"name":"Proceedings of International Radar Conference","volume":"41 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120937193","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 under non-stationary conditions, such as those experienced by an array mounted on a rapidly moving platform, performance may be significantly degraded. By modelling the dynamic behaviour of the beamforming weights the losses in performance may be recovered. In particular we show that through the estimation of a beamforming weight vector and its rate-of-change, we are able to compensate for the effects of a constant angular rotation of the array.","PeriodicalId":144063,"journal":{"name":"Proceedings of International Radar Conference","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134270622","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}
