摘要：
Compared with the optical remote sensing, microwave remote sensing has some advantages, such as penetrating clouds and all-weather observations. But one of the limitations of microwave radiometer is the relatively low intrinsic spatial resolution. In this paper, the Backus-Gilbert inversion (BGI) method and Wiener filter deconvolution technique are applied for enhan- ceeing resolution of simulation images of microwave radiometric imager (MWRI) of FY-3 satellite. A set of numerical examples sh- ows that both of them can improve the resolution of non-enhan- ced images, and Wiener deconvolution procedure achieves higher resolution enhancement while the resolution relevance of enhan- ced image is much better in BGL
