Super-resolution imaging for fully polarimetrie radar based on efficient analysis of EM scattering from objects within a half-space

Against the requirements of fully polarimetric radar for near ground or near sea targets detection, super-resolution radar imaging has been conducted in this paper, based on an efficient method for the analysis of electromagnetic scattering from 3-D objects within a half-space. By truncating the interface, the analysis of scattering from an object within a halfspace can be cast into that of a composite (high contrast) dielectric object in the free space, resulting in an efficient and accurate method by avoiding the numerical evaluations of Sommerfeld integrals totally. Based on the calculated fully polarimetric far field scattering data, radar imaging of simple manmade targets has been conducted by a super-resolution imaging algorithm, i.e., the multiple signal classification method. Numerical results are presented to demonstrate the effectiveness and accuracy of the proposed method for the analysis of electromagnetic scattering and the identification of targets near the half-space interface.
