Abstract: In this paper, we present three different kinds of motion compensation methods for stepped frequency radar, which are time domain compensation method, frequency domain compensation method and mini entropy compensation method. Then, an improved method by combining the time domain method and frequency domain method is provided. Finally, the motion compensation requested from stepped frequency radar is also mentioned.Wehner D. High Resolution Radar.
