Abstract
Aiming at the case that the defensive missiles does not have advantages in terms of maneuverability and speed,etc.based on the coordination between our targets and the defensive missiles,COPGL-CTIA is designed for intercepting the homing missiles to meet with the constraints of terminal impingement.Firstly,based on the linearization assumption,the linearized motion model is constructed,and the optimal guidance problem is constructed considering such factors as terminal miss distance,terminal impingement angle and energy consumption,etc.Secondly,by defining the zero-control miss distance to reduce the order of the state equation,the simplified optimal guidance problem is obtained.Then,the guidance command of COPGL-CTIA is solved based on variational method.Finally,the guidance performance of COPGL-CTIA is verified by the numerical simulation.The simulation results show that compared with other guidance laws,COPGL-CTIA can reduce the overload of the defensive missiles improve the interception accuracy and to achieve the terminal impingement angle constraint.关键词
