In this paper, an effectiveness evaluation method is proposed to evaluate the effectiveness of UAV group target allocation behavior, and the evaluation results are given under the background of UAV group with suicide attack ability to deal with multi-targets. The analytic hierarchy process is used to establish the evaluation index system, determine the index weight, establish the efficiency evaluation model of goal allocation, and draw the experimental conclusion by giving the quantitative numerical score of the effectiveness evaluation of goal distribution, the characteristics and effectiveness of the results of different allocation methods are compared and analyzed.
