Feasibility study on sub-pixel detection technique applied in 3.5μm band on multi-channel scanning imagery radiometer of geosynchronous orbit meteorological satellite FY-4

This article from two factors including the signal to noise ratio (SNR) and image registration accuracy, discussed the situation on 3.5um band on Multi-Channel Scanning Imagery Radiometer of geosychronous orbit meteorological satellite FY-4 used to apply sub-pixel detection technology to enhance image spatial resolution, thereby improve accuracy of fire position and calculation of fire area on the earth surface.
