Abstract

An efficient reconstruction scheme for dielectric targets is proposed based on the contrast source inversion method (CSIM). The CSIM could be preferred to the traditional Born iterative method (BIM) or its variations because it updates the contrast source and contrast simultaneously and avoids the direct solution of forward scattering integral equation (FSIE). The CSIM is similar to the modified gradient method (MGM) but it is more computationally efficient and also requires less measurement data. This is very desirable for the reconstruction when the observation is limited or measurement condition is poor. Two numerical examples with a limited observation are presented to demonstrate the approach and good images have been observed.
