Abstract
HY-2 scatterometer is a spaceborne pencil-beam radar measuring the backscattering coefficient of ocean surface. Firstly, based on the description of the working mechanism and the principle of ocean surface wind retrieval from scatterometer data, quantitative analyses of some of the typhoons captured by HY-2 scatterometer in 2012 were carried out in this paper, that include location of the typhoon center, typhoon structure, path and the radius of maximum wind speed. Secondly, ocean surface wind field was overplayed on the meteorological cloud image acquired by FY-2E satellite to reveal the consistency of spatial structure of these two sources of data. Furthermore, ocean surface wind field from ASCAT was also used to make a contrast to the ocean surface wind field of HY-2 scatterometer. Multi-angle analysis has revealed the validity of ocean surface wind field observation and the advantages of typhoon monitoring by HY-2 scatterometer. Finally, the pros and cons of the HY-2 satellite microwave scatterometer were summarized, and the possible improvements of the HY-2 scatterometer were proposed in this paper.
