For group of targets such as flock of birds, there is no need to track an individual target. Instead a cluster can be used to represent closely spaced tracks in a group.

They are adopted usually for phased arrays and compact arrays, respectively. In this study, both BF and DF are investigated for phased arrays. Particularly, using MUltiple Signal Classification (MUSIC) for direction finding in phased arrays is a subject which has received little attention. Through simulations of the first order sea clutter under various current scenarios, the mean RMS errors between radar-derived and simulated reference current profiles are examined extensively. A combination of using Barlett beamforming before and after Doppler processing is introduced to effectively increase the number of current estimates. The MUSIC algorithm has shown promising performance in target detection and current measurements when BF is used to first establish the maximum current velocity.","PeriodicalId":154440,"journal":{"name":"2013 14th International Radar Symposium (IRS)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122950904","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}
