摘　　要：激光制导航弹经过一段零指令方案飞行捕获到目标后转入末制导,在零指令方案飞行段,风标弹导引头的指向沿空速矢量方向,比例弹导引头的指向沿弹轴方向,二者相差一个角度,此角度无风时为α,有风时为αW。通过分析无风时α和有风时αW的变化规律以及制导航弹捕获目标的条件,以等效视场角的方法对比分析二者的捕获概率.通过蒙特卡洛打靶,得出二者捕获概率无显著差异的结论。The released laser-guided bomb flies along a zero-guidance command programmed trajectory. Once the target reflected laser-energy is received, the bomb will be guided towards the target until impact. During the zero-guidance command flight phase, the direction of the wind-head is along the direction of the velocity vector. And the direction of the gyro-stabilized seeker is along the direction of the body axis. The difference between these two directions is an angle. The value of this angle is a （if wind doesn＇t exist） or aw （if wind exists）. Based on the analysis of the variation characteristics of or, aw and target acquisition conditions, a comparison of target acquisition probability between these two seekers is studied with equivalent view-angle method. By Monte-Carlo simulation, it is concluded that the target acquisition probability of these two seekers is the same.
