    Abstract
  • Aiming at the phenomenon of complicated process and imperfect algorithm in the evaluation of radar anti-stealth performance, a new method for the evaluation based on improved evidence theory was presented. Firstly, to overcome the shortcomings of strong subjectivity and weak correlation, the credibility assignment function was corrected in real time according to the relationship among credibility factor, entropy weight and supported coefficient, which is based on the objective analysis of entropy theory and Euclidean distance. Secondly, combined with the multi-hierarchy indexes of radar anti-stealth performance, the rank order of whole radars anti-stealth performance on utility interval was attained. At last, an objective and accurate assessment results were obtained. The analysis of theory and simulation proved that, in contrast to other fusion algorithm, the improved fusion algorithm had better ability of assessment and better robustness.
