Theoretical and empirical models of sea surface temperature measurement are established in this paper with the analysis and processing of both remote sensing and groundtesting data.With the theoretical study of the mechanism of roughened seasurface emission,both the non-coherent double scale theoretical model of microwave emission from roughened sea surface and the foamy microwave emission model are deduced.On using calibrated empirical models, 5.40 GHZ experimental data of aircraft sensing together with its error and uncertainty are analyticallyprocessed.Finally the authors point out that it is feasible to conduct remote sensing of sea surface temperature using microwave radiometer with 1°K accuracy.
