Level 1 Products from the 2021 campaign of the airborne Ku-Band KuROS radar

This data set contains radar observations of the ocean surface . The instrument is an airborne Ku-Band Doppler radar named "KuROS".<br> This instrument was designed to measure the directional spectra of surface ocean waves , the ocean surface wind vector, and related parameters including the normalized radar cross-section profile with incidence.<br> This data set is relative to the Level 1 product, which contains the radar wave form (intensity and phase) versus range (with 1.5m resolution), the normalized radar cross-section versus incidence angle and ancillary data related to the geometry and localization of observations. The mean incidence angle of the observations is about 12.4° and the normalized radar cross-sections can be estimated from about 5° to about 20°. The observations are acquired over all azimuth angles from 0° to 360°. Level 2 data will correspond to ocean wave spectra estimated from the observations collected between 5° and 20°.<br> This data set is relative to the 2021 SUMOS campaign with 17 flights over the gulf of Biscaye, among which 13 were coordinated with CFOSAT passages.
