摘　　要：微小型巡飞弹在迎击拦截与之速度相近的运动目标时,若直接采用传统的比例导引律,由于相对速度大,会使得目标轻易的逃逸出导引头视场。针对此问题,研究主要借鉴了生物的捕食行为,生物学家发现蜻蜓在捕食过程中如果初始迎面面对目标,会迅速调整自身的飞行方向,使自身快速进入尾追状态,而后再采用尽可能平直的追踪轨迹去追击目标,以此来隐蔽自身并且使目标不会逃逸出自身视场。受此启发提出了一种与之类似的仿生复合制导律,仿真结果表明,所设计的制导律相比传统比例导引能使微小型巡飞弹在末制导过程中的需用过载更小,目标更趋近于导引头视场中心,保证了目标在制导过程中难以逃逸出导引头视场。When the small loitering munition intercepts the similar speed head-on target,if the traditional proportional guidance law is used to guide the small loitering munition directly,the target can easily escape from the field of view（FOV） of the seeker.In dealing with the problem,the predatory behavior of dragonflies is drawed on.Biologists find that when the dragonfly catches flies,if the dragonfly head-on facing the target at the initial moment,it can adjust its flight direction quickly,and make itself tail chase the target.Then the dragonfly can intercepts the target with a flat tracking path.This tracking path can conceal itself and make the target do not escape from its field of view.A similar biomimetic compound guidance law is proposed.The simulation results shows that this guidance law needs smaller normal load factor than traditional proportional guidance law in the final guidance process.It also can make the target closer to the seeker＇s field of view,and guarantees the target do not escape from the seeker＇s field of view.
