摘要
针对防区外多导弹协同突防要求导弹能够成功突破敌防御系统并击中目标的问题,提出了一种基于虚拟目标的复合制导规律。首先,在敌雷达探测范围的边缘设置虚拟目标,将导弹制导过程分为制导段Ⅰ和制导段Ⅱ。然后,研究了一种基于攻击时间和攻击角度控制的制导规律,使导弹在制导段Ⅰ按指定时间和角度追踪到虚拟目标,导弹转入制导段Ⅱ后在以攻击时间最短为指标函数的最优制导规律导引下攻击真实目标。仿真结果表明该复合制导规律大大提高了多导弹的整体突防能力。
Multiple stand-off missiles cooperative penetration requires a missile to break through the defense system of enemy and shoot the target. A combined guidance law based on virtual target is presented. Firstly, a virtual target on the edge of radar searching volume is designed to divide the guidance course into course Ⅰ and course Ⅱ. Secondly, a guidance law based on the impact time and the angle control is analyzed to pursue virtual target according to designed time and angle in course Ⅰ, then the real target is attacked by the missile by using the minimum-time guidance law in course Ⅱ. The simulation resuits indicate that the presented composite guidance law enhances the missiles＇ penetration ability greatly.
