摘要
为了提高超近程防空武器系统的有效性和效率,准确判定有效空中来袭目标。研究了从半径为R、圆心角为90°的球缺表面上任意点进入并落入地面指定防护区域a×b内的来袭目标。给出了有效来袭目标应满足的基本条件,根据来袭目标弹的射向的所有可能的八种情况,利用来袭目标中心的各种初始位置(xB0,yB0,zB0),推导了有效来袭目标的入射角应满足的条件。来袭目标有效性准则是控制子系统快速准确做出决策的依据,也是评估超近程防空武器系统捕获概率和命中毁伤概率的基础,来袭目标有效性准则可极大地提升统计模拟计算的效率。
In order to raise efficiency of aerial defence system, affirming which target in the sky is efficient is very important. This paper it discusses target which comes from spherial surface that its radius is R,angle at the centre is 90°. Firstly, it gives basic condition that efficient objective should satisfy. Secondly, basing on all kinds of angle of deviation,it deduces conditions that angle ofincidence should satisfy using defferent（ xBO,yBO,zBO ）,coordinate of target core in the low sky. The criterion provides basis for control system how to make policy quickly and accurately. The criterion is also the basis for calculating probability of destroy and probability of hit. Criterion of effective target can improve efficiency of simulator greatly.
