Weak moving target detection with multipath clutter suppression based on Hough transform

This paper focuses on the problem of weak moving target detection in dense multipath clutter environment. As a matter of fact, there is always a lot of multipath clutter remaining which will severely influence the detection performance. In the study, a method combined with entropy weighted coherent integration (EWCI) and the Hough transform is put forward. The method can effectively suppress not only the stationary clutter but also the multipath clutter. The simulation results are presented to prove the superiority of our method.
