测向交叉定位法下的反舰导弹导引头捕捉率算法

影响导弹对目标的捕捉概率的误差由目标定位误差、射击准备误差和导弹自控终点散布误差等组成.分析了在测向交叉定位法下这些误差的特性,给出了等效计算公式,并根据导弹导引头的探测特性和导弹的运动,分析了目标捕捉区域的性质,给出了区域边界的计算公式.在此基础上,提出了新的反舰导弹导引头捕捉率算法,并对它进行了计算仿真.仿真结果验证了捕捉率算法的有效性.

Calculating acquisition probability of anti-ship missile seeker to target in bearing-crossing location

The errors that affect the target acquisition probability of an anti-ship missile involve target location error,fire preparing error,and the scattering error from the missile self-control terminal.The characteristics of the errors were analyzed and the equivalent calculation formula according to the target located in bearing-crossing were given.Then according to the characteristics of detection and movement of the missile,the acquisition zone of the missile seeker to the target was investigated for the calculation of the zone boundary.Based on these work,a novel algorithm was provided for calculating the acquisition probability of the missile seeker.The validity of the algorithm was verified by simulations.
