Existing wind methods are only applicable to fully-developed, unlimited fetch seas. Here, a method is proposed for determining wind speeds for a fetch-limited sea. By differentiating the second-order radar cross section, an expression is derived, relating wind speed and the second-order peak Doppler frequency. The algorithm was tested using simulated data and has produced promising results.","PeriodicalId":447985,"journal":{"name":"2016 17th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134193042","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}
