Abstract

Based on the concept of scattering center and applying approximate scale relationship of back scattering signals in two near aspect angles, this paper adapts Mellin transform to reconstruct target´s pattern and to overcome effectively problems of features extraction caused by the factor that scattering centers are sensitive to the changes of aspect angles. By using three scale aircraft targets, the recognition experimental study has been done. The results show that the method presented in the paper is effective and feasible
