Multiple UAV Engagement Decision by Game Theory

Abstract

Importance of Unmanned Combat Aerial Vehicles (UCAVs) in air combat has been increasing continuously. Dangerous nature of air combat, limits of human body, high cost of pilot training and combat readiness create a requirement for using (UCAV) in the battlefield. High speed, limited time for making decision and multivariable nature of the problem are the main challenges of the autonomous vehicle development problem. Another challenge is coordination of air combat when performed by multiple fighters. In this article, we propose a decision-making method for multi UCAV air combat. In our method, each UCAV chooses the best engagement for the advantage of team instead of its own advantage and provide a real time feedback for improving the engagement decision. An incomplete information zero sum game implemented to antagonistic team pair. And a reduction method is proposed for mixed Nash Equilibrium strategies when large number of agents is involved. Promising results have been obtained in multi-air engagement scenario, and our solution is based on game theory approaches.
