| 摘 要： | 以搜索时间最短为设计指标,根据目标相对于拦截弹方向的概率分布,设计了一种搜索算法.分析了采用该搜索算法时,搜索范围、搜索时间以及拦截弹视场角与算法中调节系数的关系.给出了典型情况下的仿真算例,并利用统计方法分析了目标相对于拦截弹方向的概率分布的标准差对搜索时间期望值的影响.仿真表明了该搜索算法的有效性.

| Abstract: | A searching algorithm is put forward to minimize the searching time according to the distribution of the direction of the target relative to the interceptor, and the relationship between the searching aero, searching time, scope angle of the detector and the parameters in the searching algorithm is analyzed. A typical searching case is simulated and the effect of the standard deviation of the direction of the target relative to the interceptor on the mean value of the searching time is analyzed by statistic method. Simulations have shown the validity of the searching algorithm. |
