A novel velocity compensation algorithm by geometrical inference matching method

The velocity of moving target is an important factor affecting the performance of stepped frequency radar. In order to solve the problem, a novel velocity compensation algorithm is proposed. By extracting all potential scatters of two range profiles as two point patterns, the algorithm matches the point patterns by means of geometrical inference matching method. The velocity is estimated by the distance of correspondent points. The simulation experiments on range profiles with varying SNR, false scatters, and clutter aiguilles show the robustness of the new algorithm.
