Study on UCAV attack and defense game strategy under uncertain air defense fire environment

In this paper we study UCAV offensive and defensive game about the uncertain information of the anti-aircraft fire. Using game theory we build the mathematical model of the UCAV attack and defense, we describe both the offensive and defensive strategies set and get the definition of payment and calculation functions and establishing a global matrix, get the Nash equilibrium by using the method of removing inferior value rule. Finally we provide this method can improve the UCAV operational effectiveness in the midst of the battlefield with concrete instance, and provide a theoretical basis for the UCAV offensive and defensive operations.
