| Abstract: | The time frequency distribution of radar echoes of airplanes has been analysised by the wavelet transform.With the time frequency distribution, which clearly exposed the scattering characteristics of targets, this paper also applies the moments method for target recognition,and get satisfactory results. |

| Keywords: | wavelet transform time frequency analysis moments target recognition |
