However, it suffers from the difficult interpretation and poor visibility of the synthetic aperture radar(SAR) images when the weaker scattering components are masked by the nearby stronger scattering components. To overcome the drawback, a multi-view electromagnetic imaging based on attributed scattering center model is introduced. Firstly, the full aperture is divided into several overlay sub views to estimate each component's parameters. Then all components are rotated to the same view and the component's parameters information fusion is carried out. Finally, several compare experiments are provided to verify the effectiveness of the proposed algorithm.","PeriodicalId":221352,"journal":{"name":"2018 IEEE International Conference on Computational Electromagnetics (ICCEM)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114846736","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 Lagrangian density of electron gas with self-consistent electromagnetic field is established and the action of this system is discretized and minimized to obtain the discrete dynamics law. Instead of discretizing the differential equations, the variational integrator has better numerical properties in secular simulations, as it conserves the discrete Lagrangian structure and the general energy-momentum density.
