    摘要
  • 摘要: 本短文给出了欧洲空间局发射的Sentinel-1卫星合成孔径雷达(SAR)于2014年10月4日在西北太平洋获取的第一幅台风图像. 高质量SAR图像显示了台风巴蓬(Phanfone)风眼形状和海洋表面风场. 我们同时给出了海洋表面风场的提取方法. 由于欧洲空间局尚没有发布计算风场所需要的、定标的雷达散射截面系数, 实际风场计算暂时无法完成. 本研究显示了Sentinel-1卫星SAR图像在研究台风引起的海洋表面小尺度现象的优势. 本文呼吁读者充分利用Sentinel-1卫星SAR图像, 因为这是民用SAR卫星有史以来, 第一次可以免费、公开地获取SAR图像.
    Abstract: In this note, we present the first Sentinel-1 synthetic aperture radar (SAR) typhoon image acquired in the northwest Pacific on October 4, 2014. The eye shape and sea surface wind patterns associated with Typhoon Phanfone are clearly shown in the high-quality SAR image. SAR winds retrieval procedure was given but the actual wind estimates will only be available after the European Space Agency (ESA) releases the official calibration coefficients in order to accurately derive the SAR-measured normalized radar cross section. This study demonstrates the advantage of Sentinel-1 SAR with regards to imaging fine scale typhoon patterns on the sea surface beneath storm clouds. This paper also advocates the use of Sentinel-1 SAR data that is made freely and openly available worldwide for the first time in civilian SAR history.
