| 摘 要： | 根据海洋环境噪声机理及风关噪声已有的研究成果，提出利用星载微波散射计反演的海面风场数据进行海洋环境噪声分析，并对HY-2A和ASCAT数据与噪声谱级的相关性进行了对比分析。选取南海海域作为研究区，利用潜标测量系统获取的噪声数据和多源散射计风场数据开展了相关实验，并采用NCEP海面风场数据进行对比分析。结果表明，ASCAT数据与噪声的相关性优于HY-2A，散射计数据优于NCEP数据，散射计风场更适合海洋环境噪声的分析研究。该研究内容拓展了微波散射计风场数据的应用领域，并为海洋环境噪声研究提供了更好的技术手段。

| Abstract: | According to the fundamental mechanisms and recent research results of wind-generated noise, satellite-bone microwave scatterometer wind (SMSW) was applied to ocean ambient noise study in this paper. The correlation between HY-2A/ Advanced Scatterometer(ASCAT) wind and ambient noise was analyzed. The ambient noise data of subsurface buoy and SMSW in South China Sea were adopted in the experiment and the National Centers for Environmental Prediction(NCEP) wind was used in comparison. The results show that correlation between ASCAT data and ambient noise is better than HY-2A, and SMSW is better than NCEP data. The SMSW is more applicable to ambient noise study. This research expanded application field of SMSW and provided a better approached for ambient noise research. |
