舰空导弹飞行试验目标毁伤部位计算方法

摘要

In order to overcome the difficulty of analyzing warhead damage effect in ship-to-air missile flight test, a method of calculating warhead fragments damaging position of target is put forward. According to the property that dynamic scattering angle of rod warhead or focused fragment warhead is sole, the method calculates the dynamic scattering angle using optical identical frames measurement data of exterior trajectory, geometric parameters of target, etc, and then calculates the damaging position. Based on related mathematical models, the principle and steps of the method are given, and influences of relevant measurement factors to the calculating accuracy are analyzed by Monte-Carlo statistical simulation. The simulation results show that the accuracy is influenced seriously by the number and distinguish errors of identical frames, when two theodolites are distributed reasonably and the accuracy and sampling cycle of optical measurement are fixed. The conclusion is that the calculating method is validity and the accuracy can meet the need of damage analyzing.%为解决海上靶场舰空导弹拦截目标飞行试验中战斗部毁伤效果分析困难的问题，提出计算战斗部破片毁伤目标部位的方法。该方法依据杆条或聚集破片战斗部动态飞散角的唯一性，利用外弹道光学同帧画幅测量数据、目标几何参数等计算动态飞散角进而确定毁伤部位。在建立相关数学模型的基础上给出计算方法的原理和步骤，并利用蒙特卡罗统计法仿真分析相关测量因素对毁伤部位计算精度的影响。仿真结果表明：在双站单侧布站合理、经纬仪测角精度和采样周期一定的情况下，同帧画幅获取数量以及事后画幅判读误差对计算精度影响较大。目标毁伤部位计算方法正确，计算精度可以满足舰空导弹飞行试验毁伤效果分析需要。
