摘　　要：针对空间飞行器末段拦截目标制导过程中易被敌方雷达探测无法提高突防生存的问题,提出了一种空间拦截隐蔽滑模末制导律。该隐蔽制导律将主动蛇形机动信号与滑模制导律进行一体化设计,将视线倾角和偏角设计成两个切换面函数。在滑模面设计时,将饱和函数应用于控制函数中,并让两个视线角趋于零值,实现成功拦截目标卫星同时隐蔽飞行的任务。仿真验证了隐蔽末制导律不仅能实现飞行器隐蔽飞行,提高突防生存能力,而且能实现拦截目标精准制导效果。相比于比例制导律而言,隐蔽末制导律的优势在于提高命中敌方概率的同时提高了突防能力。In order to solve the problem that it is easy to be detected by enemy radar in the course of terminal interception guidance,a stealthy sliding mode terminal guidance law for space interception is proposed.The stealth guidance law integrated the active serpentine maneuver signal and the sliding mode guidance law.The inclination and declination of the line of sight are designed as two switching plane functions.Meanwhile,the saturation function is applied to the control function in the sliding mode plane design,and the two line of sight angles approached to zero.Simulation results show that the covert terminal guidance law can not only realize the covert flight of aircraft,improve the penetration survival ability,but also achieve the precise guidance effect of intercepting targets.Compared with the proportional guidance law,the advantage of covert terminal guidance law is to improve the probability of hitting the enemy while improving the covert survival performance.
