Abstract:

According to the character of optic-uided cruise missiles, a real-ime path planning scheme is presented. A model of permitted course area of missiles is established under contrary light conditions, and combining it with the other flight constraint conditions of cruise missiles, the search space of the A* algorithm is planned. Aiming at the inefficient planning way of smoothing all the digital terrain in the traditional A* algorithm, a new A* algorithm which only real-time smooths the possible path by each search step is proposed. Simulation results show that the new A* algorithm is suitable for optic-guided cruise missiles and has more efficiencythan the traditional one.
