以特殊角度攻击地面固定目标的圆周导引律
Circular guidance law against stationary target with specified impact angle
摘要
Abstract
Aiming at the problem that impact on the ground stationary target with specified angle is required for some guided missiles,a circular guidance law which only uses the line⁃of⁃sight angle information for terminal velocity direction control was de⁃rived.The idea of this approach is to guide the missile following a series of circular arcs determined by the specified impact angle and the real⁃time position of the missile and the target.Based on the simple geometrical principle,the required velocity inclination angle can be quickly worked out,which is then used for guidance command generation. Simulation results show that compared with the typical optimal guidance law,the circular guidance law presented is more favorable to the case of overhead⁃attack and is less af⁃fected by guidance periods,but is more affected by guidance order delay.关键词
