用WFFT替代某雷达MTI时的窗函数优化分析

Analysis of Optimum Window for Replacing MTI Filter by WFFT Filter Bank

将WFFT替代某雷达(M雷达)中的MTI方法以抑制杂波.对各种窗用于M雷达时的窗函数及通道 将数优化选择作了分析,并对其抑制杂波效果作了比较,得到了相关结论,为提高M雷达的杂波抑制性能提供了理论依据.

Replacing MTI filter in a certain radar (Radar M) by WFFT filter bank, this paper presents the analysis of the existing windows used for WFFT to suppress clutter, compares the clutter suppression performance for various windows, and come to the relative conclusions from the simulation results, which lays a theoretical base of boosting clutter suppression performance for Radar M.
