Super-Resolution Imaging For Objects Within A Half Space Based On Fully Polarimetric Radar
This paper is based on the application requirements of fully polarimetric radar for near ground and 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 half-space 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.Using the calculated fully polarimetric far field scattering data,radar imaging of simple manmade targets has been conducted by a super-resolution imaging algorithm.Differences of electromagnetic scattering characteristics of some manmade targets with different heights above ground or sea and the radar images are also have been compared.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.
