摘要: |
本文利用小波变换对五种飞机目标的雷达回波进行时频分析, 得到了回波信号的时频分布图。全面清楚地描述了目标的散射特性。文中通过提取时频分布图的矩特征作为目标特征量, 对五种飞机的目标作了识别实验, 取得了良好的识别效果。 |

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 |
