The measured spacing between adjacent beams in a seven element array is 0.64 degrees. A four element array has also been used for tracking.","PeriodicalId":314918,"journal":{"name":"1983 Eighth International Conference on Infrared and Millimeter Waves","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129429491","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}
