Abstract: Based on researching binary-coded range side-lobe suppression problem for radar pulse

compressed signal, the radial basis function (RBF) neural network was optimize d with the improved evolutionary planning algorithm (IEPA), a new algorithm based on the improved evolutionary planning algorithm was presented. IEPA was combined with neural network by the new algorithm, multi-layer feed-forward neural network structure was replaced with RBF neural network structure, and back propagation (BP) algorithm was replaced with IEPA, then, expected side -lobe suppression quota was rapidly waisted. The emulation experiments for the 13-elements baker code and 31-elements M code show that side -lobe suppression ability and operating speed was improved with the new method.

Key Words: Side-lobe suppression; Pulse compression; Evolutionary planning

1 引言

脉冲压缩技术在现代雷达中得到了广泛的应用

其中二相编码信号就是

一种比较常用的脉冲压缩信号

信号的主旁瓣比较低

所以常常需要进一步抑制副

即时域加权[1, 2, 3]和频域加权[4]

文献[5]研究了采用13位巴克码和63

位M 编码时脉冲雷达检测的神经网络方法

为二相编码旁瓣

抑制问题的处理提供了一个新的途径

不同的信号差异较大

且容易陷入局部最小值
