摘要:

针对机载捷联导弹打击地面移动目标场景下中末制导交班点处的目标捕获问题,研究了弹体位置散布、姿态散布和目标散布3个要素对于红外导引头捕获概率的影响,利用函数误差分析推导了视线角均方差的解析表达式,并建立了当前点和前置点两种攻击方式下导弹捕获概率解析模型。仿真结果验证了模型的正确性,并可以据此确定可打击目标的运动速度范围。

Abstract:

The acquisition of a ground-moving target at the terminal guidance hand-over point in the scenario of an airborne strapdown missile attacking the target is investigated.The influences of three key factors,including missile position dispersion,attitude dispersion,and target dispersion,on the acquisition probability of infrared seeker are studied.Then the analytical expression for the mean square error of line-of-sight angle is derived based on functional error analysis.Furthermore,an analytical model of acquisition probability under two attack modes,namely current point and pre-point,is established.Simulated results verify the model’s accuracy,which enables determining the range of moving velocity of target that can be engaged.
