我们报告的检索方向海粗糙度（全方向均方斜率，包括MSS，方向和各向同性）通过反演全球导航卫星系统反射（GNSS-R）和太阳反射光谱（SORES）在1000米的实验飞行期间收集的数据。重点是利用整个延迟-多普勒图（用于GNSS-R）或全方位角图（用于SORES）来推断这些方向参数。得到的估计进行了分析和比较，贾森-1测量和ECMWF数值天气模式。
We report on the retrieval of directional sea-roughness (the full directional mean square slope, including MSS, direction and isotropy) through inversion of Global Navigation Satellite System Reflections (GNSS-R) and SOlar REflectance Speculometry (SORES)data collected during an experimental flight at 1000 m. The emphasis is on the utilization of the entire Delay-Doppler Map (for GNSS-R) or Tilt Azimuth Map (for SORES) in order to infer these directional parameters. Obtained estimations are analyzed and compared to Jason-1 measurements and the ECMWF numerical weather model.
