Direct targeting and engagement with airborne satellite guided weapon

摘要: 介绍了卫星制导武器直接瞄准攻击方式在对地精确打击中占据的关键位置，阐述了卫星制导武器直接瞄准攻击方法的原理。由于卫星制导武器直接瞄准攻击对目标定位要求较高，采用常用定位手段已不能满足系统对目标定位的要求，分析了使用相对GPS制导成为卫星制导武器直接瞄准攻击的关键的原因。相对GPS制导误差主要包括采用载机和武器相对GPS定位误差以及传感器对目标的相对定位误差，分别对两者的定位精度进行了分析和推导。仿真结果表明：这两者的综合误差理论值小于7.5 m，满足卫星制导武器在直接瞄准攻击中对目标定位的需求。Abstract: Direct attack with satellite guided weapon is one of the most important means for precision ground strike. The direct attack operation needs high precision target position, which cannot be satisfied by conventional positioning methods. The relative GPS guidance is the key technology for airborne satellite guided weapon direct attack. This paper presented the direct attack concept of satellite guided weapon, and analyzed the errors of relative GPS guidance technology. The errors were induced by relative GPS position and airborne sensor relative position. The position precisions of them were analyzed. The simulation results indicated that the overall error of the relative GPS guidance was less than 7.5 m, which satisfied the requirement for the satellite guided weapon direct attack.
