摘　　要：本文研究相控阵机载预警(AEW)雷达针对旋翼回波信号特点的检测技术，提出 了采用时空 级联自适应处理(TSA)杂波抑制结合多多普勒通道联合检测的方法，并导出了 具有恒虚警率( CFAR)特性的检测器结构.理论分析和仿真实验证明了这种检测器的可行性和 有效性.This paper studies the detection method of hovering helicopter with phased array airborne early warning(AEW) radar.The approach to detect the flash echo-signal from blades of a hovering helicopter is proposed,which is used by the Multi Do ppler Channel Joint(MCL) detection and Time Space Cascad ed Adaptive(TSA) proce ssing to suppress clutter.The configuration of detector is given,the performance of the detector is analyzed,and the feasibility and eff ectiveness are verified with Monte Carlo test.
