| 摘 要： | 海洋内波在合成孔径雷达(SAR)图像中具有特定纹理分布,因此可以根据海洋内波SAR图像的纹理分布特性,进行内波海面特征检测。利用功率谱对具有不同纹理特征的SAR图像进行分析,并对特征进行分类统计得出内波的功率谱特征。在海洋内波区域,利用多孔小波变换及多尺度融合提取海洋内波特征,在此基础上对波-流散射系数进行提取。提出了"内波特征的功率谱特征-多孔小波综合检测算法",为海洋内波参数反演奠定了基础。 |
| 关 键 词： | 海洋内波 特征检测 功率谱 多孔小波 SAR图像 |

| Abstract: | The ocean internal wave has specific vein distribution in the synthetic aperture radar（SAR） image,so we can detect the surface feature of the internal wave according to the distribution characteristic.We make use of power spectrum method to analysis SAR images with different vein distributions,it can get power spectrum features of internal waves from classify and statistic.In ocean internal wave areas,adopting a＇trous wavelet transformation and multiscale fusion to extract features of internal waves,we can get wave-current interaction scattering coefficient.At last,we get power spectrum-a＇trous wavelet detection method of internal wave feature,the base of internal wave parameter anti-calculation. |
| Keywords: | internal wave feature detction power spectrum a＇trous wavelet SAR image |
