According to the needs of performance evaluation of intelligent radar information processing， the performance evaluation index system of intelligent radar information processing was constructed from three technologies including target detection， target recognition， and residual clutter suppression. The attribute hierarchy model was improved by replacing the proportion scale with the score scale， and the index system was weighted by the improved attribute hierarchy model. In the evaluation model， the grey correlation analysis method was introduced， and the grey correlation coefficient was used to replace the Euclidean distance. The improved technique for order preference by similarity to the ideal solution method was used to rank the performance of different intelligent radar schemes， and the optimal intelligent radar technology scheme was screened out. The effectiveness of this method was verified by the working data of intelligent radars.
