This model has been applied extensively in microwave engineering, e.g., frequency selective surface (FSS). Firstly, we develop a deterministic RCS solver based on nodal Discontinuous Galerkin Finite Element Method (DG-FEM). Then we quantify the RCS mean and variance of a 2-D cylinder with random holes based on the stochastic collocation method. We use the Gauss-Patterson quadrature formula to solve the resulting stochastic equation. Numerical results show how the RCS in scattering is affected by the uncertainty in shape of the object.","PeriodicalId":280404,"journal":{"name":"2009 3rd IEEE International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115486253","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 reflected signal from the encoding transponder to SAR can be imaged with the background clutters suppressed. One type of encoding transponder inverts the chirp slope of a linear frequency modulation (LFM) signal transmitted by the SAR. Two methods exist by which the transponder can invert the chirp slope of a LFM signal from the SAR: the analog mixing method and the digital undersampling method. I put forth the latter method in this paper as being the superior approach.
