空空导弹中制导律的适用性研究

对三种典型中制导律攻击多种目标的适用性进行了研究。首先,将空空导弹所攻击的目标按照运动特性进行了分类;然后,对比例导引、奇异摄动和弹道形成三种典型中制导律的性能及适用性进行了深入分析,并进行了仿真验证。仿真结果表明：比例导引规律能量消耗大、速度低,但指向误差小;奇异摄动方法消耗小、速度快,但指向误差大,适用于攻击按照固定轨迹飞行的目标;弹道形成方法在能量和速度方面的性能介于两者之间,指向误差小,适用于攻击可以进行机动规避导弹攻击的目标。

Research on Applicability of Midcourse Guidance Laws for Air-to-Air Missile

This paper studies the applicability of three typical midcourse guidance law for manifold targets.Based on classfying the targets of air-to-air missile,the performance and applicability of proportional navigation guidance law,singular perturbation guidance law and trajectory shaping guidance law are analysed and simulated.The results of simulation show that the proportional navigation wastes most energy and obtains small final velocity,but its pointing error is small;the singular perturbation guidance law w...
