Other AbstractMicrowave microwave polarimeter is a sensor of measuring not only the vertical-and horizontal-polarization,but also the third and/or the forth Stokes parameters.It realizes all information about electromagnetic wave,including frequency,phase,amp litude and polarization,to be measured by a senor.The correlated information of the first two Stokes parameters is more sensitive to the anisotropy of the ocean surface.Wind direction retrieval is one of the initialmotivations of the polarimeter development.In this paper,the p rogress and characteristic on polarimeter development are introduced and theories of ocean wind vector remote sensing are analyzed.Oceanic emission and scattering model is develoked for remote sensing wind vector using passive polarimetric microwave radiometer.The critical techniques on its system design, which include receiver and calibration methods,are discussed in order to realize scientific target of wind retrievals. Furthermore more efforts are paid on expatiating scientific top ics on wind reversion methods,including geophysical model function built2up, influences ofmain technical specifications on retrieval precision,and wind direction ambiguity removalmethods by data2p rocessingmethods and scanning geometry. The calibration errors and main specifi-cations of polarimetric radiometer, which have significant influences on the accuracy of wind vector retrieval,are summed in detail. Finally, a new scanning geometrywith fore2aft2look to remove wind direction ambiguous solution is put forward.
