Considering the influence of remote support jamming,the effectiveness evaluation index and the corresponding quantitative rules are put forward.AHP and entropy weight method are used to determine the weight of index.Considering the logical relationship among indexes,the aggregation method is improved,and index system is established to reflect equipment efficiency more accurately.The algorithm of efficiency aggregation based on matrix operation is proposed,which contains the ability of dealing with uncertain information,and the ability of aggregating efficiency of indexes which restrict each other.Based on the improved method and effectiveness evaluation,efficiency of warning radar in remote standoff jamming is simulated,which proves the feasibility of the improved method.It also provides decision-making basis for the evaluation of the effectiveness of single radar in remote standoff jamming and sorting of radar performances.
