| 摘 要： | 基于时频分析的性质，提出了一种雷达目标识别方法。对雷达回波信号进行小波变换，得到目标回波信号的三维时频分布图和功率谱密度，从中提取目标的调制谱密度，根据最小贴近度识别算法进行目标识别。由实验结果看，利用此方法能够得到很高的识别率。 |
| 关 键 词： | Morlet小波变换 目标识别 调制谱 |

| Abstract: | Basing on the properties of wavelet transform, a method is presented in this paper. The process is dealing with the echo by wavelet transform, obtaining 3D-time- frequency distribution and power spectral density, extracting modulating spectral density, then identifying target. The experimental result shows that the method is effective. |
| Keywords: | Morlet wavelet transform Radar target identification Modulating spectrum |
