Abstract:

In the process of multiple unmanned aerial vehicles (UAV) cooperative penetration, to address the challenges of model construction and the high complexity of solving target allocation and detection jamming and reconnaissance action selection tasks, an improved method of Monte Carlo tree search (MCTS) is proposed to realize joint multi-mission decision making for multiple UAVs. First, a unified mathematical decision model for multi-UAV target allocation and reconnaissance actions is constructed, considering the situational factors such as angle and distance in the confrontation between UAV and radars, as well as the current probability of successful execution of UAV actions and the effective probability of radar states. An improved MCTS algorithm with adaptive adjustment of search frequency is proposed for fast online optimization in large solution spaces. Simulation results show that the improved algorithm decreases the threat level of multi-radar system to UAVs by about 16.8%, improves the effect of the algorithm compared to the multi-armed gambling machine by about 5.08%, and the decision time is about 0.23 s, which is about 45.7% shorter than that of the traditional MCTS, thereby improving UAV battlefield survivability.

Key words: multi-UAV collaboration, task joint decision, target assignment, Monte Carlo tree search (MCTS)
