　　针对机载火控雷达在地面运动目标检测模式下主杂波多普勒频率随距离单元快变的特点，分析机载火控雷达地面运动目标检测特点，提出一种基于最小二乘估计的多普勒频移补偿方法，以实例进行仿真验证，并与常规处理方法和3DT-STAP方法进行对比。结果表明：在低重频模式下，该算法能自适应的进行多普勒频移补偿，提高雷达系统地面运动目标检测能力，优于其他2种类似方法。

Aiming at the main cluster Doppler frequency fast varying following the distance unite airborne fire control radar under ground moving target detection mode, analyzed airborne fire control radar ground moving target detection feature, put forwards the Doppler frequency shift compensation method based on least squares estimation. Use example to carry out simulation and verification. Compare regular resolution method with 3DT-STAP method. The results show that, under low repetition frequency mode, the method can self-adaptive carry out Doppler frequency compensation, improve radar system ground moving target detection ability. The method is better than other 2 methods.
