摘要

海面微波后向散射与海面风致粗糙度密切相关。该特性用于获得全球海洋表面矢量风。由于信号水平较弱，目前部署的散射计尚未使用交叉极化海面回波(VH，代表垂直发射水平接收或水平发射垂直接收)。然而，在高风速下，特别是在低入射角下，共极化回波(VV或HH)可能会饱和。

A C-band cross polarization geophysical model function

Microwave backscattering from the ocean surface is closely related to the wind-generated ocean surface roughness. This property is used for obtaining global ocean surface vector winds. The deployed scatterometers so far do not use the cross-polarized sea return (VH, representing either vertical transmit horizontal receive or horizontal transmit vertical receive) because of its weak signal level. The copolarized returns (VV or HH), however, may saturate in high wind speeds especially for low incidence angles.
