考虑干扰的影响，提出警戒雷达效能评估指标和相应的量化规则，采用层次分析法和熵权法确定指标的权重，充分考虑警戒雷达工作过程中不同指标之间的逻辑关系，改进警戒雷达效能指标单一的聚合方式，建立效能评估指标体系，更加准确地反映装备的真实效能；提出了基于矩阵运算的效能聚合算法，有效地将处理不确定信息的能力和制约关系指标的效能聚合能力进行兼容；借助云模型理论，对评估结果进行可视化处理，并提出吸引度的概念和最大吸引度的决策原则。采用对警戒雷达在远程支援干扰下的工作效能进行实例分析，取得较好的结果，证明了改进方法的可行性。为单部警戒雷达在干扰环境中的效能评估和多部雷达的性能优劣排序提供决策依据。

Considering the influence of interference, the effectiveness evaluation indexes and corresponding quantization rules of warning radar are put forward. The weights of indexes are determined by AHP and entropy weight method. Considering the logical relationship among indexes, the aggregation method is improved, and index system is established to reflect the equipment efficiency more accurately. The algorithm of efficiency aggregation based on matrix operation is proposed, which contains the ability to deal with uncertain information, and the ability to aggregate the efficiency of indexes which restrict each other. The evaluation results are visualized by cloud model theory, and the concept of the attraction degree, and the principle of maximum attraction are put forward. The effectiveness of the warning radar under remote support jamming is analyzed, and good results are obtained. The feasibility of the improved method is proved. It provides decision basis for performance evaluation of single radar in jamming environment and performance ranking of multiple radars.
