摘　　要：运动补偿是频率步进雷达应用中的难点之一,基于频率步进雷达理论,针对频率步进雷达对高速目标距离成像失真的问题,提出了一种消除距离像失真的方法。该方法在已知目标距离和速度估计值的情况下,可以很好地消除距离像失真,同时获得高精度距离分辨率。结合仿真实验和实测数据分析验证了方法的正确性和精确性,可以为其他的运动补偿处理提供有力的支撑。Velocity compensation is one of the difficulties of application in stepped frequency radar. Based on the theory of stepped frequency radar, for the range profiling of high speed targets in stepped frequency radar, a new method to eliminate the distortion of the range profile was proposed in this paper. If the good estimates of the target velocity and range are known, the distortion can be well reduced and the high range resolution profile can be well accomplished. This method is verified by both simulation and experimental data, which provide powerful support for future motion compensation processing.
