摘要
分析了空地制导炸弹综合飞行/火力控制系统(integrated flight/fire control,IFFC)构成,以此为平台,对IFFC系统的核心内容——动态火控解算算法展开研究。基于角度积分的方式,提出弹道末端变步长角度积分算法,应用于快速、准确地模拟投放域;以快速解算算法为基础,建立连续计算投放域(continuously computed release region,CCRR)的数学模型,推导方向、距离瞄准原理公式,实现对地作战的自动瞄准、攻击。仿真结果验证了算法的良好性能,达到了很好的作战效果,适用于严格要求实时性、精确性及灵活性的机载作战任务软件设计。
The composition of Integrated Flight / Fire Control（ IFFC） system of air-to-ground guided bombs is discussed in this paper. A platform based on IFFC is applied to researching the core content of the IFFC system- dynamic fire control calculation algorithm. For the purpose of simulating release region fast and accurately,we propose ballistic final stage variable step integration algorithm,which optimizes the angle integration method. The mathematical model of Continuously Computed Release Region（ CCRR） based on the fast calculation algorithm is established and the direction,distance aiming principle formula of CCRR is derived,which achieves the auto-aiming and autoattacking of air-to-ground bomb. The simulation results show good performance of the algorithm,which attains good combat effectiveness. The algorithm proposed by us can be applied to the design of airborne combat assignment software,which requires real-time capability,accuracy and flexibility strictly.
