Yuheng Xu, Siyi Cheng, Zhongying Suo, Wanze Zheng · 2019
In view of the shortcomings of the existing radar emitter threat evaluation, the model is applied to emitter threat evaluation by utilizing the uncertainty problem processing ability and delayed decision making ability of intuitionistic fuzzy set(IFS)-three-way decision(TWD) model. Firstly, five PDW parameters of radar emitter are extracted, fuzzy matrix of target set and attribute set and weight matrix of PDW parameters are constructed, and then fuzzy transformation is used to construct synthetic intuitionistic fuzzy set matrix. Then, an intuitionistic fuzzy set-three-way decision model is constructed by combining threshold value and intuitionistic fuzzy set matrix. Finally, the threat degree of emitter is evaluated according to the model. The experimental results show that the model overcomes the uncertainty in the process of processing and avoids the judgment error easily caused by two-way decision. The emitter is divided into different domains according to the degree of emitter threat, and the emitter threat evaluation is realized with high speed and reliability.
