Evaluation and Comparison Model for Combat Efficiency of EW System Based on Ideal Grey Relational Projection

针对电子战系统作战效能的评估比较问题，基于灰色系统理论和矢量投影方法，提出了一种新的基于理想灰关联投影的分析模型和算法，介绍了该方法的基本原理和一些基本概念，建立了系统作战效能与正、负理想作战效能之间接近程度的分析模型，总结了用该方法进行比较分析的一般步骤；并提出了一种基于效能区分度的比较灵敏度分析方法。实际算例验证了所提作战效能比较分析模型和比较灵敏度分析方法的可行性和有效性，该方法为电子战系统作战效能的评估比较提供了一种新思路。

Using the grey system theory and the vector projection synthetically, a new model for the combat efficiency evaluation and comparison of EW system based on similarity to ideal grey relational projection was put forward. The principle of the algorithm and some basic concepts were introduced. The comparative model was set up, in which the adjacency degree both between the combat efficiency and the positive ideal combat efficiency and between the combat efficiency and the negative ideal combat efficiency is taken into account synchronously. And the general analysis steps using the model were summarized. Then the method for comparison sensitivity analysis based on the distinguishing degree of the combat efficiency was presented. At last, the feasibility and effectiveness of the proposed comparison model and the sensitivity analysis method were proved by an example. The model offers a new way for the combat efficiency comparison of EW system.
