根据导引设备平台高速变攻角运动和探测环境的特点,研究了弹载雷达和红外导引系统的探测能力以及最佳的探测条件,利用最优化理论,建立了再入机动弹道模型,仿真分析了最大机动距离弹道和最小机动距离弹道对导引装置探测性能的影响。结果表明,针对不同的导引头,采用不同的机动弹道将有助于导引头性能的发挥,从而进一步提高导弹的命中精度。

Firstly,the detective capability of missile-borne radar and IR seeker are studied based on the moving characteristics of guidance equipment platforms and detective environment.Secondly,the mathematic model of reentry maneuverable trajectory is built by using optimization theory.Finally,the influences of max/min maneuverable trajectory on detective capability of seekers are analyzed through simulation.The result shows that different seekers adapting to corresponding maneuverable trajectories can improve missile hit accuracy.
