摘要
分析了悬停直升机旋翼的回波信号特点,分析了利用弹载高重频脉冲多普勒雷达对悬停直升机进行检测的可能途径和可利用信息。提出了一种似然比检测方案,分析了其检测性能,最后给出了对具体型号的悬停直升机进行检测的仿真结果。
This paper studied the characteristics of the echo from the hovering helicopter, analized the methods and the signal that could be used to detect the hovering helicopter using the HPRF pulsed Doppler radar.Then Proposed a detection methods based on the likelihood and analized its performance.At last ,The experiment result Aiming at a hovering helicopter,this paper is given.
