Dynamic Route Planning Algorithm with Impact Time Control

To achieve the tactics mission of cooperative attack at the fixed impact time, for multiple route planning anti-ship missiles, a dynamic route planning algorithm with impact time control is proposed. First, a recursive route planning algorithm is designed to choose navigation points and come to a reference route. Then, in order to control the impact time, the reference route is re-planned on line according to the error time between the fixed impact time and the estimated time to go. If the error time is positive, the reference route from the current navigation point to the next one is extended by maneuvering fly; if the error time is negative, the reference route is shorten by adjusting the location of navigation point. The realization of controlling the impact time is transferred to dynamically increase or decrease distance of the reference route. The simulation results show the validity and effectiveness of the proposed algorithm.
