摘要：
In this paper, we focus on motion compensation of moving target with a constant acceleration in randomized stepped frequency inverse synthetic radar (RSF ISAR). A novel target motion compensation method called minimum entropy of accumulated Doppler spectrum method is proposed. The method compensates the quadratic phase first, and then estimates radial velocity. The method can overcome the influence on radial velocity estimation caused by radial acceleration, and keep the benefit of overcome range profile de-focus problem. Simulation results show that the proposed method is effective for motion compensation and robust to the signal-noise ratio (SNR).
