The KOMPSAT-3A is a high-resolution optical satellite launched in 2015 by Korea Aerospace Research Institute (KARI). KOMPSAT-3A provides Panchromatic (PAN-0.55 m), Multispectral (MS-2.2 m), and Mid-wavelength infrared (MIROR-5.5 m) image. However, due to security or military problems, MIROR image with 5.5m spatial resolution are provided down sampled at 33 m spatial resolution (MIRrd). In this study, we propose spatial sharpening method to improve the spatial resolution of MIRrd image (33 m) using virtual High Frequency (HF) image and optimal fusion factor. Using MS image and MIRrd image, we generated virtual high resolution (5.5 m) MIRORfus image and then compared them to actual high-resolution MIROR image. The test results show that the proposed method merges the spatial resolution of MS image and the spectral information of MIRrd image efficiently.
