摘　　要：根据某型雷达的具体情况 ,MTD的滤波器组采用了切比雪夫加权设计方法 ,对相关的信号处理方法如恒虚警检测等关键问题作了讨论。测试结果表明 ,该 MTD系统对地杂波的抑制比大于 5 5 d B,对动杂波的抑制比大于 45 d B。A Chebyshev weighted Doppler filter bank is adopted for a new type of radar. In this paper, the relevant processing method is described and the key problems such as CFAR detection are discussed. The experiment results show that the rejection radio of MTD system to the ground clutter is greater than 55 dB, and the rejection radio of MTD system to the moving clutter is greater than 45 dB.
