摘要
为了研究图像制导导弹采用导引搜索时目标的进场概率,建立了目标作不同机动的模型,并将测量误差引入到模型中。在一定的目标信息中断时间和测量误差下,利用统计试验法对目标的捕获概率进行了研究。仿真结果表明:当采用导引搜索时,目标的捕获概率受测量误差影响较小,它随目标信息中断时间的增大而明显减小;当中断时间达6s时,捕获目标的概率保持在0.7以上。
To study the target catching probability of image guided missile,a model of various maneuverability flight of helicoptcr is founded and left-to-right guided searching program and several measuring errors are introduced.Statistics method is used to obtain the target catching probability when time interval and measuring errors of target flight informa- tion obtaining are considered.Simulation shows target catching probability changes little when measuring errors are dif- ferent and decreases as time interval of target flight information obtaining increases.It keeps over 0.7 when time inter- val reaches 6 seconds if guided searching program is used.
