Description

Technical field[0001]The invention relates to a multi-angle strike trajectory planning method for formation drones based on a grid planning algorithm, which belongs to the technical field of autonomous trajectory planning.Background technique[0002]With the increasing complexity of the modern battlefield environment, UAVs have been more widely used than manned aircraft due to their low cost, flexible operations, diverse functions, and strong battlefield survivability, and are more suitable for performing dangerous tasks in harsh environments. The formation of multiple UAVs is one of the important ways of UAV collaboration, making the execution of tasks more flexible. UAV formations have a higher probability of damage to enemy targets from multiple angles, and are the mainstream trend and important role of future street fighting and air-to-ground operations. Driven by the demands of battlefield operations, UAV formation operations have gradually become a necessary capability for weapo...
