Within-visual-range air combat maneuver decision-making in obstructed environments via a curriculum self-play soft actor-critic with an attention mechanism

This is the authors' abstract. We don't add key points for this paper.

With the rapid development of artificial intelligence, intelligent air combat maneuver decision-making (ACMD) has garnered global attention. Although deep reinforcement learning provides a promising approach to ACMD, existing methods often suffer from rigid reward functions and limited adaptability to evolving adversarial strategies. Moreover, most research assumes open airspace, overlooking the influence of potential obstacles. In this paper, we address one-on-one within-visual-range ACMD in obstructed environments, and propose an improved Soft Actor-Critic (SAC) algorithm trained under a curriculum self-play framework. A maneuver strategy mirroring inference module is integrated to estimate each other's likely positions when visual obstruction occurs. By leveraging curriculum learning to guide progressive experience accumulation and self-play for adversarial evolution, our method enhances both training efficiency and tactical diversity. We further integrate an attention mechanism that dynamically adjusts the weights of sub-rewards, enabling the learned policy to adapt to rapidly changing air combat situations. Numerical simulations demonstrate that our enhanced SAC converges more quickly and achieves higher win rates than other baseline methods.
