Contrast Source Inversion Algorithm Against Three Dimensional Microwave Experimental Data

摘要

This paper describes a nonlinear inversion scheme for reconstructing two three-dimensional (3-D) homogeneous dielectric targets in an anechoic chamber in a controlled environment. The applied scheme is the contrast source inversion (CSI) algorithm, a nonlinear iterative algorithm based on two domain integral equations, combined with frequency hopping (FH) approach. The inversion results, which are presented and compared for the 3-D co-polarized data, verify the capability and the accuracy of the CSI algorithm with CF approach for 3-D microwave imaging.
