Compared with traditional linear frequency modulation scheme, phase-coded ISAL can refer to the methods in communication to reduce noise interference or compensate the carrier phase error. In this paper, a novel single sideband modulation based phased coded continuous-wave ISAL system is proposed and experimentally demonstrated. The spectral efficiency of the new system is twice that of the traditional system, resulting in twice the utilization of echo energy. In addition, the use of continuous wave modulation improves anti-noise capability and imaging quality. Imaging results with azimuth resolution of 1.51cm are obtained by two 4cm aperture diameter telescopes at the distance of 7km, achieved about twenty times higher than conventional real aperture imaging system.","PeriodicalId":293734,"journal":{"name":"2022 International Applied Computational Electromagnetics Society Symposium (ACES-China)","volume":"267 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115308201","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}

The first resonator is a dual-mode coaxial cavity achieved by adding a sleeve to a conventional coaxial metal post, while the second one is a single-mode resonator. By cascading them together, the fundamental modes of two cavities are used to form a passband. This special configuration and port position can introduce two transmission zeros above the passband, which leads to high selectivity. To verify the design concept, a BPF operating at 2.06GHz with the bandwidth of 160MHz is designed and simulated.","PeriodicalId":293734,"journal":{"name":"2022 International Applied Computational Electromagnetics Society Symposium (ACES-China)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115465993","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}
