基于空时极化处理的机载雷达非平稳杂波抑制方法
Airborne radar non-stationary clutter suppression method based on space-time-polarization processing
摘要
Abstract
The traditional azimuth-Doppler domain space-time adaptive processing(STAP)method is unable to distinguish the clutter of different ambiguous distance units,and thus it is difficult to effectively suppress the short-range non-stationary clutter.In order to solve the aforementioned problem,this paper proposes a non-station-ary clutter suppression method for airborne radar based on space-time-polarization processing.The method intro-duces the polarization dimension information of the echo on the basis of the pitch-azimuth-Doppler 3D-STAP method,and then performs the polarization-pitch-azimuth-Doppler 4D joint spatial polarization adaptive process-ing on the echo signal.The simulation results show that compared with the traditional azimuth-Doppler domain STAP method and the pitch-azimuth-Doppler 3D-STAP method,the proposed method can realize the suppression of non-stationary clutter more effectively.关键词
