A recognition method of radar target is presented based on wavelet transform and Mahalanobis range in this paper. First, after computing wavelet transform of radar echo, target scattering centers are obtained in range profile. Then the target characteristics are extracted by computing Mahalanobis range of every scattering center. The experiments of recognition using the data of three kinds of aircraft models were performed and demonstrated that the method has high recognition rate and low sensitivity to noi...
