N2 - 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, which indicates that the deconvolution technique is feasible to enhance the spatial resolution of MMSI. In the analysis of the antenna temperature of the earth obtained by MMSI, We consider the effect of beam scanning and acquire an accurate estimate of the brightness temperature distribution. The results show that the outline of the typhoon in the enhanced image is closer to the initial image than the non-enhanced image. The correlation coefficient is improved and the spatial resolution is enhanced from 96km to 57km, which indicates the effectiveness.
