摘要
利用最优线性二次型的形式 ,以脱靶量和需用横向加速度综合最小为导引指标 ,建立了一种能应用于主动雷达导引头的最优未制导律模型 ,并从工程应用的角度出发 ,设计了次优未制导律模型。以某主动雷达型空空导弹为例进行了大量的弹道仿真研究 ,并与比例导引律相比较。统计的仿真结果表明所设计的次优导引律的弹道比比例导引律平直 ,平均耗用过载少 16 .1% ,命中概率高 53%。
A optimal guidance law(OGL) which synthetically minimize navigation bias and required vertical acceleration, is developed by the means of Linear Quadratic Regulator(LQR). And this guidance is applicable to the active radar guided air to air missile in this paper. To reach the aim of engineering application, a sub optimal guidance law(SOGL) is designed . Lots of simulation results show that the performances of SOGL are tatter than of proportional navigation: the required vertical accelerations decrease by 16.1%, and the inteception rates increase by 53%.
