Ground moving targets detection and relocation in heterogeneous environment for airborne radar based on tri-channel real data

This paper describes an approach for ground moving targets detection and relocation in heterogeneous environment which requires three consecutive operations as follows: Firstly, some deleterious factors correction techniques are adopted before clutter rejection. Secondly, different window selection strategies, aiming at different image coregistration error, are given to form the joint data vector for clutter rejection. Finally, the true target steering vector is derived in the presence of image coregistration error and channel mismatch, based on which the radial velocities of moving targets can be determined. Results of measured data processing are included to verify the robustness of this algorithm.
