摘要
角闪烁是雷达目标后向散射特性的重要物理量 ,它能严重降低毫米波末制导雷达的导引精度。介绍了一种利用RCS和角闪烁之间的相关性抑制角闪烁的RCS加权方法。为实现这一方法 ,采用了频率捷变技术来获取目标回波信号的多个独立样本。仿真结果显示 ,经过 4至 5个脉冲的处理 ,角闪烁的均方根线偏差从 5m～ 6m降至不到 1m。
Angular glint is an important parameter of radar target's back - scattering characteristics. It seriously reduces guidance accuracy of millimeter radar. In this paper, we propose a way to suppress the angular glint by utilizing the crosscorrelation between RCS and angular glint. To accomplish this RCS weighting method, frequency agility is employed to get independent samples of target echo signal. The simulation result shows that the square root error value of glint can be suppressed from 5m [similar to] 6m to no greater than 1m within 4 [similar to] 5 pulses processed.
