Abstract

Abstract

Based on the China Academy of Space Technology airborne spectrometer test data and the ECMWF wind data, the average backscattering cross sections, asymmetry and anisotropy changed with the incidence angle under different wind speed conditions, and the reason of wave backscatter asymmetry and anisotropy were preliminary analyzed. The results showed that at low incidence angle, the average backscattering cross section decreased as the incidence angle increased and reached a stable value at 18°,after essentially unchanged;wave backscatter asymmetry and anisotropy increased as incidence angle increased, reached a stable value at 18°, after essentially unchanged; under small winds speed conditions, waves asymmetry and anisotropy were related with wind speed, and the anisotropy and asymmetry were more obvious as wind speed increased.
