摘要

摘要:
为提高红外成像制导导弹的破片式战斗部打击军用飞机的毁伤效能，以典型对地作战飞机为研究对象，提出2种情况下破片式战斗部对飞机的瞄准点选择方法。建立对地作战飞机易损性模型和战斗部破片飞散模型，以此为基础采用射击线法计算作战飞机的毁伤概率。对于不考虑引信探测过程的情况，建立基于导弹制导误差的战斗部毁伤效能指标，用于选择给定打击方向下的瞄准点；对于考虑引信探测过程的情况，根据引信探测仿真和导弹制导误差确定炸点位置，采用蒙特卡罗法计算各炸点毁伤概率均值，进而获得各打击方向下的最优瞄准点。通过仿真算例对红外制导地空导弹打击下的瞄准点选择方法进行分析研究，结果表明：不考虑引信探测过程的瞄准点选择方法得到的最优瞄准点分布在机体边缘，而考虑引信探测过程的瞄准点选择方法得到的最优瞄准点会向机体中心偏移。

Abstract:
To improve the damage efficiency of infrared imaging guided missile fragment warhead against military aircraft, a typical air-to-ground combat aircraft is taken as the research object, and the aim point selection method of fragmentation warhead against combat aircraft in two case is proposed. Based on the vulnerability model and warhead fragment dispersion model of aircraft, the damage probability of aircraft is calculated by using shot line method. For the case that the fuze detection process is not considered, the warhead damage efficiency index based on missile guidance error is established to select the aim point under the given attack direction. For the case that the fuze detection process is considered, the location of the explosion point is determined according to the fuze simulation and missile guidance error. Monte Carlo method is used to calculate the average damage probability of each explosion point, and then the optimal aim point in each attack direction is obtained. The aim point selection method under the attack of infrared guided surface-to-air missile is analyzed and studied through the simulation example. The results indicate that the optimal distribution of aim point is on the edge of the body when the case that the fuze detection process is ignored, and the optimal aiming point will be offset to the body center when the process fuze detection is considered.
