| 摘要: |
| 提出了一种基于Dopplerlet变换的舰船辐射噪声特征提取方法，给出了Dopplerlet变换分解流程。使用此种方法及基于小波变换、波形结构、自然尺度等的特征提取方法对收集到的舰船辐射噪声进行了识别试验，试验结果证明基于Dopplerlet变换的舰船辐射噪声特征提取方法更加有效。 |

| Abstract: |
| A novel approach of warship radio noise feature extraction using Dopplerlet transform was proposed in this paper, and decompose flow of Dopplerlet transform was typed. An experimentation of warship radio noise classification was tried out using different feature extraction methods, such as Dopplerlet transform method, wavelet transform method, wave structure method and natural measure method. Experimentation result shows that the warship radio noise feature extraction method using Dopplerlet transform is more effective than other methods. |
