Abstract :
Deconvolution technique is used in vertical polarization channel brightness temperature data of Microwave thermometer of FY-3 satellite for improving the ground spatial resolution. This paper applies the technique to the simulation images of MWTS and compares the experiment results firstly. Then the real data of MWTS is resolved, the relative geometry of every data samples changes over the scan due to the conical scanning of the instrument. The changes are resolved through designing different point-spread- function for every data in the reconstruction technique. The technique is applied in the Greece region, results indicate that, with the deconvolution technique, it is feasible to enhance the spatial resolution of MWTS, islands and the coast line in the enhanced express more details than non-enhanced brightness temperature images.
