Abstract

Traditional radar imaging has difficulties in imaging moving targets due to Doppler shifts induced in the imagery and limited spatial resolution of the target. We propose a method that uses a multiresolution processing technique that sharpens the ambiguity function of moving objects to remove Doppler induced imaging errors and improves instantaneous resolution. This method allows for instantaneous imaging of both static an moving objects in a computationally efficient manner thereby allowing more real time radar imagery generation.
