摘　　要：由于经典比例导引规律对大气层外高性能目标的命中精度不理想,文中就此问题提出了一种改进的比例导引规律。该导引规律的改进之处有两点:①提出了目标飞行弹道的预估算法,保证了导弹对目标位置和速度的实时预估,解决了红外导引头带宽限制的问题;②以减小脱靶量为指标,提出了较优导航比例系数的搜索算法,解决了弹体可用过载限制的问题。仿真结果表明,这种改进的比例导引规律对高性能目标能够取得较高的命中精度,相比经典的比例导引规律有很大的性能改善。In this paper, an advanced proportional guidance law is proposed since the classical proportional guidance law gets low precision when used to intercept high - powered targets. The proposed guidance law contains two algorithms ： one is estimating the target ＇ s trajectory under the bandwidth limitation of the infrared lead, and the other is searching for an optimized proportional coefficient under the limitation of the overload. The simulation results demonstrate the advanced proportional guidance law , which has greater performance than the classical guidance law, can achieve high precision when intercepting the high - powered targets.
