摘要：

The results of a study to determine the correlation of the surface scattering cross section per unit at normal incidence sigmao(0o) and 13.9 GHz with surface wind speed are presented. Comparing sigmao(0o) measurements with ship reports of wind speed, it was found that an algorithm could be decised which is capable of producing wind speed estimates from sigmao(0o) measurements to a precision of 2.6 m/s for winds in the range of 1-21 m/s. Correlations with buoy measurements in the range of 1-10 m/s show an rms precision of 2.1 m/s with the possibility of a slight bias in the ship report based algorithm.-from Author
