| 摘 要： | 为了减少对方进行电子对抗的机会,要求反舰导弹末制导雷达在保证一次捕获概率的同时尽可能减小角度搜索范围.为此,提出了一次捕捉概率为1的最小角度搜索范围模型.模型中,用圆分布表示目标指示误差和目标机动误差,用矩形分布表示自控终点散布误差.首先证明了末制导雷达开机位置与最小角度搜索范围之间存在的几个性质,进而利用解析方法推导了最小角度搜索范围表达式.分别以末制导雷达最大作用距离和导弹被发现距离为可变参数,对高亚声速反舰导弹末制导雷达的最小角度搜索范围进行了计算.结果表明,最小角度搜索范围不超过36.5°,小于某些反舰导弹的最小角度搜索范围.

| Abstract: | In order to reduce chance disturbed by electronic counter measures(ECM),the terminal guidance radar of an anti-ship missile should capture the target in its first scan period,and the search angle should be as small as possible.A model of minimal search angle is presented while the target acquisition probability of terminal guidance radar in its first scan period reaches 1.In the model,the target indication error and target maneuvering error are both supposed as circular distribution,and the terminal dispers... |
