Mechanically scanned radars are expensive and limited by a short dwell time on target. An electronically scanned array is an attractive solution, but requires large numbers of transceivers. MIMO permits thinning of the array without compromising image quality. Each transmitter element is encoded with a unique sequence. A problem is Doppler, due to target and platform motion. This restricts the selection of sequences. We present suitable sequences and a signal processing scheme.","PeriodicalId":103180,"journal":{"name":"2016 IEEE 2nd Australian Microwave Symposium (AMS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134413388","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 peak directivity of the ERA with P-PCS increases by 9 dB, which is similar to that achieved by height varying dielectric PCS. The P-PCS is an attractive alternative because of its planar geometry and 73% smaller thickness as compared with height-varying dielectric PCS.","PeriodicalId":103180,"journal":{"name":"2016 IEEE 2nd Australian Microwave Symposium (AMS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122020834","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}
