摘要
为提高导弹在攻击角度约束下对机动目标的拦截效能,提出了一种基于相对速度矢量控制的制导策略.通过运动矢量合成建立了虚拟的相对运动坐标系,将常速拦截机动目标问题转化为变速攻击静止目标问题,并基于二阶贝塞尔曲线设计了满足相对航迹角约束的相对运动轨迹,使用轨迹跟踪算法生成制导指令以控制相对速度矢量.仿真结果验证了所提制导律的有效性和优越性.
Abstract
To improve the effectiveness of missiles against a maneuvering target with an impact angle fixed,a guid-ance strategy based on relative velocity vector control is proposed. A virtual relative motion coordinate system is es-tablished by motion vector synthesis,which transforms the problem of intercepting a maneuvering target under con-stant velocity into the problem of impacting a stationary target under time-varying velocity. Then a relative motion trajectory satisfying the relative heading angle constraint is designed based on a quadratic Bezier curve,and a traj ec-tory tracking algorithm is employed to generate guidance commands to control the relative velocity vector. Simula-tion results verify the effectiveness and superiority of the proposed guidance law.
