Harris' Hawk and Pigeon Inspired Attack-Defense Decision Making in Unmanned Combat Aerial Vehicles

The collective behavior of groups of birds has attracted researchers' attention by its fascinating patterns when escaping threats or hunting preys. This paper addresses the attack-defense decision making of unmanned combat aerial vehicles (UCAVs) inspired by the mechanisms of Harris Hawks hunting preys and pigeons defending predators. A predator-prey based dynamics is adopted to guide two adversarial teams of UCAVs separately. The roles of attackers and defenders are determined according to a situation function and two different kinds of decision making approaches are proposed, which are inspired from Harris Hawks hunting behavior and pigeons defending behavior, respectively. It is the first time to our knowledge to study the combat decision-making problem from the predator-prey perspective and the simulation results show the feasibility of the proposed approaches.
