%X Spaceborne polarimetric microwave radiometer WindSat can provide the effective measurement for the ocean surface wind vector.The brightness temperatures measured by WindSat need geolocation process.Geolocation is an important part of WindSat data calibration and validation.In this paper,a modified geolocation algorithm of Patt94 is used for WindSat.The evaluation process is presented and the errors are analyzed.By simulating WindSat orbit,possible error sources and their influences are described.Finally,a method for radiometer attitude correction is discussed.
