Abstract: Aimming at the problem of air target recognition with multiple characteristic indexes，a new fusion method based on the cosine of vector inclination is proposed.The method normalizes the feature vectors of the reference mode and sensor information，uses the vector inclination cosine of the reference mode and sensor information to determine the Basic Probability Assignment（BPA） for all possible targets’ evidence.The result of target recognition is presented according to the D-S evidence combination rule.The example analysis proves that the method is effective.

Key words: multi-sensor, information fusion, target recognition, evidence theory
