Wind Speed and Direction Measurement Using Microwave Polarimetric Radiometers

摘要

The determination of both wind speed and direction from microwave radiometermeasurements of the sea surface is considered. The near-nadir polarimetric technique is analyzed. The physical phenomena, determining the azimuthal and polarization dependence of brightness temperature, are discussed. Main attention is paid to the overview of experimental results, obtained by Russian and American researchers during the last fifteen years. The comparison of different microwave remote sensing techniques for wind vector recovery shows the advantage of the full-polarization radiometer measurements.
