Abstract:

To address the problem of target attack time coordination and route space coordination of multiple UAVs, a multi-UAV four-dimensional cooperative attack route generation algorithm based on the T/S-SAS (Time/Space Dual Cooperative Sparse A* Search) algorithm is proposed. The flight expansion node model is improved, an algorithm structure based on concurrent expansion is designed, and a cost calculation model for time coordination as well as a multi-UAV anti-collision constraint model are established. Simulations are performed. The results show that the proposed algorithm can enhance the planning efficiency of UAV attack route, shorten the range in coordination time for different drones to reach the target, and solve the anti-collision problem for different UAVs. The multi-UAV cooperative attack route can meet the time/space constraints, allowing the multi-UAV strike performance at cooperative time and the flight route space coordination performance to be improved, and the operational efficiency and capability of multi-UAV cooperative combat to be increased.
