摘　　要：为解决末制导炮弹在一个周期完成对目标的搜索捕捉态势问题,首先确定末制导雷达的开机点范围、捕捉概率模型的差异与开机距离的直接关系;然后,综合考虑目标散布误差、自控终点散布误差、发射平台定位误差、偏航角等误差因素的影响,并将其作为圆分布来处理;最后,以末制导雷达在一个周期内完成搜索时的开机距离为基础,分情况建立在上述误差综合作用下的末制导炮弹对目标的捕捉概率计算模型,并仿真分析了捕捉概率随导引头开机距离、末制导炮弹速度、发射距离以及各误差的变化趋势。仿真结果表明:影响末制导炮弹捕捉概率的主要因素是导引头开机距离和搜索范围,同时也不可忽视其他各误差对捕捉概率的影响。Aims at the situation of terminal guided projectile searching and capturing target in one cycle.The starting point range of seeker was calculated and the influence of target position dispersion error,terminal dispersion error,launching platform positioning error,yaw angle and other error factors were treated as circular distribution.The calculation model of catching probability of terminal gui-dance projectile under the above error synthesis was established,and the variation trend of capture probability with starting point of seeker,velocity of terminal guided projectile,firing distance and errors were simulated.The simulation results show that the main factor affecting the capture probabi-lity of terminal guidance projectile is the starting point of seeker and search range;meanwhile,the influence of each error on the capture probability cannot be ignored.
