Ground Moving Target Imaging using Bi-static Synthetic Aperture Radar

In this paper, we present a novel method for imaging of moving targets using bi-static synthetic aperture radar configurations. We present a forward model that maps the two-dimensional reflectivity and velocity of targets to the measured scattered field data. We then introduce a filtered-backprojection type method to reconstruct the reflectivity and use Renyi entropy to determine the two-dimensional velocity of targets. The filter is determined so that the reflectivity images are reconstructed at the correct location, orientation and strength whenever the velocity field is determined correctly. We present numerical simulations to verify our theory.
