In view of the end-guidance process of intercepting ballistic missiles intercepted by atmospheric kinetic energy interceptor in atmosphere, a new optimal guidance law is proposed. Due to the adoption of a new method for calculating the remaining time, the acceleration command generated by this optimal guidance law can be realized by the trajectory control system of the interceptor, which is controlled by the longitudinal axis of the projectile. Finally, the numerical simulation of the interception process is carried out using the new optimal guidance law and the traditional proportional guidance law respectively. The simulation results show the effectiveness of the new optimal guidance law.
