The deconvolution technique for spatial resolution enhancement of MMSI on FY-4 satellite

The deconvolution technique can improve the spatial resolution of Millimeter and Sub-millimeter Sounding/Imager (MMSI) of FY-4 satellite. In this paper, the technique is applied to the simulated brightness temperature image of a typhoon scene of MMSI, which indicates that the deconvolution technique is feasible to enhance the spatial resolution of MWSI. The typhoon's brightness temperature in the enhanced image displays more details. Outline of the typhoon is closer to initial image than non-enhanced image. The correlation coefficient is improved and spatial resolution is enhanced twice, which indicates the effectiveness of this technique.
