A Novel Method of EW System Effectiveness Evaluation Based on Conflict Status Association Analysis

Abstract

Electronic Warfare (EW) effectiveness evaluation plays an important role in promoting the development of EW technology, promoting the construction of EW equipment systems, and improving the operational capability of the system. Due to the incomplete information caused by the non-cooperative nature of EW, the data of the evaluation index, which are used for effectiveness evaluation, are in Grey scale. In order to approach these problems, we develop a novel method for EW effectiveness evaluation based on Conflict Status Grey Correlation analysis. Specifically, based on conflict theory and correlation theory, an analysis model for the approximation degree of the observation status and expected status of EW is established. Then we introduce the status Grey relational analysis method. The effectiveness value is acquired through the function correlation of the approximation values of both sides, and then we propose an evaluation discrimination method based on status robustness and correlation discrimination. At the same time, we evaluate the effect of errors in the observed values on the evaluation results. The simulation example results show that the proposed model is rational and feasible. This method can effectively overcome the problem of single-angle evaluation of the system and solves the issue of high dependence of traditional EW effectiveness evaluation theory on target data.
