However, jammer motion cannot be handled by the existing VAT beamforming approaches. In order to solve the problem, a robust VAT beamforming approach against jammer motion is proposed. The Kronecker product of the virtual array covariance matrix is used for beamforming. The interference component in the covariance matrix is greatly strengthened and a bunch of virtual interference is created, so wide nulls can be obtained, by which jammer motion can be effectively inhibited. The validity of the proposed approach is verified by theoretical analysis and simulation results.","PeriodicalId":247909,"journal":{"name":"2019 International Applied Computational Electromagnetics Society Symposium - China (ACES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129952985","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}
