In this paper, the transformation of Gaussian beam modes of co-polarization and cross-polarization in 2D multi-reflector system based on Gaussian beam mode analysis (GBMA) is described in detail and some significant expressions are given and discussed. Then we proposed a fast analysis method based on vector addition method. In order to verify the validity and accuracy of this approach, we compare the results of our algorithm and PO in commercial software GRASP10 with some examples of conic surface mirrors containing the amplitude and phase.","PeriodicalId":423474,"journal":{"name":"2019 12th UK-Europe-China Workshop on Millimeter Waves and Terahertz Technologies (UCMMT)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127792791","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}

Underwater acoustic signals, noticeably, can cause tiny displacements on the water surface. These displacements contain the information of sound sources and therefore can be extracted by terahertz radar. This paper at first presents both a point target model for narrow-beam terahertz radar and a face model for wide-beam terahertz radar. The face model is established according to the facet method. The radar echo is then simulated according to the different models and the time-frequency analysis of the surface vibration is carried out. The effective water-surface vibration model will lay a foundation for information extraction of underwater sound sources and eventually for communication.","PeriodicalId":423474,"journal":{"name":"2019 12th UK-Europe-China Workshop on Millimeter Waves and Terahertz Technologies (UCMMT)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124671349","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}
