Preliminary Evaluation of Sentinel-1A Wind Speed Retrievals.
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing（2016）
摘要
The accuracy of wind speed retrievals from synthetic aperture radars (SARs) is strongly dependent upon the accuracy of the normalized radar cross section measurement. Here, we make a preliminary assessment of wind speed retrievals from Sentinel-1A. In particular, we use Sentinel-1A SAR imagery to compute wind speed at 500-m resolution. These measurements are averaged to 25 km and compared with adv...
