Study on the Spatial Resolution Enhancing Technology of FengYun Satellite Microwave Remote Sensing with Wavelet Transform

This paper focuses on the imaging principles of spaceborne microwave imagers, with particular emphasis on the microwave remote sensing spatial resolution enhancement techniques developed for the Fengyun satellite. Building upon these advancements, image resolution enhancement algorithms were employed to achieve further improvements in image resolution.First, this paper introduces the development history of China's Fengyun meteorological remote sensing satellites, as well as the research progress and current status of resolution enhancement technologies for meteorological satellite remote sensing images both domestically and internationally.Subsequently, common spatial resolution enhancement and matching techniques were introduced, with particular emphasis on deriving the principles of the Wiener filter deconvolution algorithm. This algorithm was then selected to enhance both simulated and measured data resolutions. Building on this foundation, the focus shifted to enhancing image spatial resolution. The wavelet transform method was employed for further image enhancement. Using this algorithm, after the satellite image data has undergone spatial resolution enhancement and matching processing, further resolution improvement can be achieved, effectively highlighting the image's detailed features.
