Dynamic Programming Guidance Law for Maneuvering Target

In order to solve the interception problem for maneuvering target, a dynamic programming guidance law is proposed. Firstly, under the condition that the acceleration information of the target is unknown, according to the current position and velocity of the target, the optimization indexes including minimum remaining attack time and minimum miss distance are designed. Secondly, based on the above optimization indexes, considering the control constraints of interceptor missile, the online planning scheme of guidance command is proposed for non-game maneuvering target and game maneuvering target respectively. Finally, the simulation is designed to test the performance of the guidance law for targets with various maneuvering behaviors. The simulation results show that the dynamic programming guidance law can effectively guide the interceptor missile under control constraints to intercept maneuvering targets, and has good adaptability and convergence.
