Research on Close Air Combat Modeling of Differential Games for Unmanned Combat Air Vehicles

Based on a six-degree-of-freedom model of unmanned combat air vehicles(UCAVs),a differential countermeasure was combined with computer game for the problem of autonomous decision of UCAVs in air combat.The traditional differential game model which uses angle advantage as payoff function was improved by introducing changing value in the computer game for reference.When UCAV is in different air combat situation,the model embodies the real air combat situation of that the different incomes are obtained with the change of the same angle,so it makes the air combat strategies more intelligent and more reasonable.The simulation results show that the algorithm is rational and effective.
