摘　　要：研究常规雷达利用旋翼回波信号来探测悬停直升机目标的方法。提出了针对旋翼回波信号的多普勒通道联合检测方法 ,分析并给出了检测器的结构和性能。蒙特卡洛试验结果验证了检测器的有效性。This paper studies the detection problem of hovering helicopter with normal coherent radar. The approach to detecting the flash echo signal from blades of a hovering helicopter, which is based on the technical of “Multi Doppler Channels Joint Detection”is put forward. The configuration of detector is given. The performance of the detector is analyzed theoretically, and the effectiveness is verified with Monte Carlo experiments.
