针对缺少不完整复制信号在雷达接收机上的检测性能的研究,提出了对不完整复制信号在雷达中的检测性能进行分析的方法.该方法对不完整复制的常规信号和LFM信号进行了建模,分析了上述信号在雷达中的检测性能,为客观评估该类信号在雷达中产生的干扰效果提供了理论依据.仿真验证表明,两种不完整复制的信号都可以在雷达中被检测,在适当的复制长度和信噪比条件下,不完整复制信号可以获得和原信号十分接近的发现概率.
The radar detection performance of the partly copied signal has not be studied at present.The partly copied signal detection performance analysis method was presented in this paper.The routine partly copied signal and LFM signal were modeled and the detection performance of radar were studied.The results of the simulation indicated that the two kind signals could be detected by radar.The finding probability of the partly copied signal was very close to the original signal at a likely copied length and SNR.
