针对无人战机(UCAV)在空战格斗中的自主决策问题,在UCAV的六自由度模型的基础上,将微分对策与机器博弈相结合;通过引入机器博弈中的“变值”思想,改进了传统的以“角度优势”作为支付函数的微分对策模型。当UCAV处于不同的空战态势时,该模型体现了同样的角度变化所获得的收益不同的真实状况,使UCAV的空战策略能够更趋智能与合理,仿真结果验证了算法的合理性与有效性。 According to UCAV’s autonomous decision-making in air combat, based on UCAV’s six-degree-of-freedom model, differential game is combined with machine game. By introducing the idea of ​​“variable value” in machine game, Improved the traditional differential game model with “angle advantage ” as the payment function. When the UCAV is in different air combat situations, the model shows the real situation of different gains from the same angle changes, which makes the UCAV air combat strategy more intelligent and reasonable. The simulation results verify the rationality and effectiveness of the UCAV.
