| 摘 要： | 对于空间分集雷达,各雷达站与目标的距离不同会引起信噪比的不同,从而降低传统的非相干积累检测器的检测性能.基于尼曼-皮尔逊准则,提出一种对各站接收信号进行基于信噪比加权的信号融合检测器.在已知各站回波信噪比的条件下,它可以达到检测性能的上界.数值试验表明,该检测器的检测性能较传统的非相干积累检测器有明显改善,特别在信噪比较低时.

| Abstract: | For a spatial diversity radar,signals received by widely separated radar sites may have different signal-noise-ratios(SNRs) due to different distances between radar sites and target,which would decrease the detection performance of the conventional incoherent accumulating detector(IAD).Based on the Neyman-Pearson criterion,a signal fusion based target detection algorithm is proposed,which weights signals received by different radar sites according to channel SNRs estimated.With channel SNRs of radar sites k... |
