Adaptive weapon-target assignment for multi-target interception

In this paper, an adaptive weapon-target assignment (WTA) model is proposed for multi-to-multi interception by taking the normal overload of missiles as the benefit factor and the uniform distribution of resources as the main constraint. Firstly, the total demand normal overload is considered as the basis of WTA, and an allocation strategy based on the attenuation model of target value for a variety of constraints to model the WTA problem is proposed. Secondly, in order to reduce the acceleration cost, an analytical expression of the whole-course overload is derived under the proportional navigation guidance, so that the overload of the whole combat process can be estimated at the initial moment according to the initial information of the missile and target. Then, based on the genetic algorithm, the WTA method is designed. Finally, the assignment method is verified in a multi-to-multi interception mission.
