Abstract  

FY-3 MWHS scans the Earth's surface by mechanically rotating the antenna around X-axis.This research presents a geolocation method for FY-3 MWHS' remote sensing image based its scan geometry.It creates the spatial relationship model between the sensed data and the Earth based coordinate system,according to MWHS' sensing geometry and the sensor's attitude and position.This method is also including an algorithm of satellite orbit computation,which is used to get the satellite's instantaneous velocity vector from its position vectors.This method has been applied to FY-3 MWHS' remote sensing image geolocation.The geolocation result and error analysis use the land/water mask.Compared the geolocation results with the true remote sensing image,it shows that this method for MWHS' remote sensing image achieves pixel geolocation accuracy.

Key words:  MWHS      Sensing geometry modeling      Geolocation
