侧窗探测自适应制导研究

A New Adaptive Proportional Navigation Based on Side Window Detection

为增强配置侧窗导引头的导弹的探测和跟踪目标的能力,在比例导引的基础上提出了一种随导弹速度前置角变化的自适应比例导引,随后在自适应比例导引的基础上通过引入目标加速度补偿项得到了一种针对目标机动的自适应增广比例导引,通过研究这两种制导律的脱靶量和导弹速度前置角范围,得到了侧窗探测条件下制导律的适用范围,最后基于导引弹道仿真与传统比例导引和平行接近法进行了仿真比较。仿真结果表明,侧窗探测条件下自适应比例导引和自适应增广比例导引有效且适用范围更广。

To enhance the ability of detecting and tracking targets for missiles with side window seekers,a new adaptive proportional navigation with the change of the missile＇s lead angle is presented based on proportional navigation. Then,a new adaptive augmented proportional navigation is proposed for maneuvering target by introducing the target＇s acceleration compensation term on the basis of the adaptive proportional navigation. By studying the miss distance and the range of missile＇s lead angle of these two kinds of guidance law,the application range of the guidance law is obtained under side window detection. Finally,the simulation is compared with that of the traditional proportional navigation and the constant bearing navigation. Simulation results show that the adaptive proportional navigation and the adaptive augmented proportional navigation are effective and both have a wider range of application under side window detection.
