摘要： 利用20 Hz高采样雷达测高数据和准同步卫星图像对南海和苏禄海的内波进行了调查。分析了雷达测高数据对内波调制的响应特性和频带敏感性。通过准同步观测，分别讨论了Ku波段和C波段的Sigma0和有效波高（SWH）对调制的响应。结果表明，对于 Sigma0，Ku 波段更敏感，而 C 波段对 SWH 更敏感。利用雷达测高高采样数据与MODIS影像准同步观测，计算了南海和苏禄海内波的传播速度。计算得到的内波速度与KdV方程求得的相速度接近。该工作表明，可以从雷达测高高采样数据中提取内波的定量参数。测高数据可以作为内波研究的附加数据源。
ABSTRACT The 20 Hz high sampling radar altimetry data and quasi-synchronous satellite images are applied to investigate internal waves in the South China Sea (SCS) and the Sulu Sea. The response characteristics and band sensitivities of radar altimetry data to the modulation of internal waves were analysed. With quasi-synchronous observations, the responses of Sigma0 and significant wave height (SWH) in the Ku band and the C band to the modulation were discussed, respectively. The results demonstrate that for Sigma0, the Ku band is more sensitive, whereas the C band is more sensitive for SWH. The propagation speeds of internal waves in the SCS and the Sulu Sea were calculated with quasi-synchronous observation of radar altimetry high sampling data and MODIS images. The calculated speed of the internal waves is close to the phase speed obtained from the KdV equation. This work indicates that the quantitative parameter of internal waves could be extracted from radar altimetry high sampling data. The altimetry data could serve as an additional data source for the investigation of internal waves.
