Aircraft Route Planning and Local Dynamic Obstacle Avoidance

This paper proposes a track planning method based on optimized A* algorithm and a dynamic window method path planning method under sudden threats. Using a real geographic elevation data model, the global path of the aircraft is obtained by using the A* algorithm planning after the improvement of the Dubins curve. This paper analyzes the sudden dynamic threats and external obstacles that may be encountered by the aircraft during flight, and uses the DWA algorithm to achieve the dynamic local obstacle avoidance goal, and simulates the simulation to verify the feasibility of the proposed method.
