摘　　要：从杂波特性入手,讨论了对运动杂波进行自适应抑制的必要性。理论分析了杂波自适应抑制技术,并进行了仿真验证。针对工程实际中多普勒频率估计不够精确的情况,提出在杂波多普勒频率粗估计的基础上采用多个自适应滤波器,根据输出功率比较确定最佳杂波抑制滤波器,大大提高了系统性能,并且不需要很大的设备量。The necessity of the adaptive suppression for the moving clutters based on the clutter characteristics is discussed.The technology of the adaptive clutter suppression is analyzed theoretically,and the simulation and verification are made.In view of the fact that it is difficult to obtain the adequately accurate evaluation of the Doppler frequency in engineering applications,the multiple adaptive filters are adopted based on the coarse evaluation of the Doppler frequency of the clutters.The optimal clutter suppression filters are determined by comparing the output power,which greatly improve the performances of the system with less equipment.
