摘　　要：针对雷达辐射源信号识别效能评估方法杂乱,指标模糊等问题,提出一种基于I2TOPSIS雷达辐射源信号识别效能评估方法。该方法主要在以下三点对传统区间TOPSIS方法进行改进:利用熵值计算指标权值;利用理论极值确定正负理想点;利用区间距离计算评估方案到正负理想点的距离,并将I2TOPSIS方法应用于雷达辐射源信号识别效能评估中得到一种新的雷达辐射源信号识别效能评估方法。最后通过与传统区间TOPSIS方法的评估对比实验证明新方法所得结果更合理、可行。In order to solve the problems that radar emitter signal recognition evaluation methods are messy and evalua-tion indexes are confusing,a novel radar emitter signal recognition evaluation method based on I2 TOPSIS is put forward. There are three improving points compared with the traditional TOPSIS method.That is using the entropy to build index weights,using theoretical extreme value to determine the ideal point and negative ideal point,using interval distance to compute the distance between evaluation plan and ideal and negative ideal points.Then use the I2 TOPSIS method in effec-tiveness evaluation of radar emitter signal recognition.At last a comparing simulation between the novel method and tradi-tional TOPSIS method is done,whose results prove that the novel method is more reasonable and feasible.
