Abstract: In order to solve the problems of radar signal recognition methods in fuzzy evaluation index selection, single method for index weight determination and unreasonable assessment order, an improved radar signal recognition evaluation method based on IAHP-Entropy-I2TOPSIS model is put forward. The method builds tree viewer evaluation indexes system based on measurement of recognition rate. In this model, the subject and object weight are calculated by IAHP and Entropy method. The linear combination method is used to determine the comprehensive weight. ITOPSIS method is optimized by using the method of inclination measurement for interval multi-attribute decision-making. The optimization method is I2TOPSIS, which is used to evaluate and order. Finally, the results of case simulation show the validity of the proposed method.
