摘要
针对传统空空导弹攻击区解算过程较慢的问题,结合变步长积分、气动系数拟合及最大最小边界快速搜索算法,建立了一种基于三自由度弹道模型的空空导弹攻击区快速解算方法。仿真结果表明,该算法在满足计算精度要求的前提下,大大提高了攻击区的解算速度,保证了机载武器系统的实时性要求,对火控系统实时解算攻击区边界具有重要的参考意义。
Aiming at the problem that traditional solution of air-to-air missile attacking area was slow, based on missile three-degree-of-freedom motion model,a model was established by combining step-changed integration,pneumatic factor fitting and fast search of maximum/minimum boundary. Simulation result shows that this algorithm can improve the computational speed with high computational accuracy.It ensures the real-time demand of airborne weapon system, which has an important significance in solving real-time fire control system.
