基于DSM-CSI的非线性逆散射算法研究
DSM-CSI Based NonIinear Inverse Scattering Method for Co mpIex Objects Reconstruction
摘要
Abstract
Due to the absence of information concerning the location and number of scattering objects in inverse scat-tering problem,it results in nonlinear inverse scattering method calling for high refactoring space dimension and high compu-tational cost.Based on the low computational burden with the linear inverse scattering methods in reconstructing the location and number of the targets,we propose a nonlinear inverse scattering method in this paper,which combined with DSM linear and CSI nonlinear inverse scattering methods.The reconstruction results of DSM are used as the prior information to provide the location and the number of the targets for the CSI method,which reduce the dimension of refactoring space and the a-mount of computation.Experimental results show the effectiveness of the proposed method.关键词
