Abstract
Some autofocusing techniques for the motion compensation in Inverse Synthetic Aperture Radar Imaging of object are proposed. These techniques are based on the maximization of a suitably defined contrast function which represents a measure of the degree of focus of the image. A theoretical analysis of these techniques is performed and some results achieved by means of a simulation program are presented and discussed.
