A GPS antenna should cover a wide spatial angle to receive the maximum number of GPS signals but not too wide because jamming signals usually comes from a low elevation angle. Proposed system uses MUSIC algorithm to estimate DOA of jammers and Taguchi's Optimization Method to find optimum amplitude weight values in order to steer radiation nulls toward the jammer's directions while maintain the main beam constant. Proposed system can easily be replaced with conventional GPS antenna to improve GPS receiver jamming mitigation capabilities.","PeriodicalId":422501,"journal":{"name":"2017 25th Telecommunication Forum (TELFOR)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131560671","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}
