In this paper, a novel AIP determination method is proposed based on the fusion of datum acquired by the ascending and descending orbits. Firstly, the influence of AIP error on the InSAR positioning is analyzed. The horizontal shift directions introduced by the AIP bias for ascending- and descending orbit data are different. Then, the AIP can be determined by minimization of the height difference between ascending- and descending-orbit data. The effectiveness of the proposed method is validated by the experiment with TanDEM-X SAR data.","PeriodicalId":331510,"journal":{"name":"2022 3rd China International SAR Symposium (CISS)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130632490","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}

Due to the spectrum aliasing caused by antenna rotation of TOPS SAR, traditional imaging algorithms usually adopt twostep processing to avoid spectrum aliasing. However, these algorithms require zero-padding, which makes the computation cost high. Moreover, the range cell migration (RCM) of the higher term is ignored and additional RCM is introduced in the range cell migration correction (RCMC) processing, which lead to defocused imaging results in the case of long integrated time. In order to solve the above problems, an effective TOPS SAR imaging algorithm is proposed in the paper. The simulations on point targets and GF-3 data show the effectiveness of the proposed imaging algorithm.","PeriodicalId":331510,"journal":{"name":"2022 3rd China International SAR Symposium (CISS)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122914682","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}
