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. According to the 3.5um band on Multi-Channel Scanning Imagery Radiometer of geosychronous orbit meteorological satellite FY-4 needs to detect fog and area with fire on the earth surface at two different characteristics of the target,the 3.5um band has two different pre-amplifier gain settings and different indicators of spatial resolution,the two parameters can be adopted by the atmosphere transmission equation and detectors’ responding to the energy of 3.5um band on Multi-Channel Scanning Imagery *** 3.5um band on Multi-Channel Scanning Imagery Radiometer used to detect areas with fire on the earth surface has a particular target which is area with fire on the earth surface with characteristic of high energy,as a result,using sub-pixel detection technology improves the 3.5um band’s spatial resolution under the stars from 4000m to the nearly 2000m,besides,the signal to noise ratio(SNR) in image after dropping 8～10dB aroused by image reconstruction still meet the system *** shows that as long as the phase error of the original image sequence brought about by instability of the scanning mirror’s speed is less than 10%of the pixel,the effect of phase error to the image reconstruction can be *** the measurement of the scanning mirror’s instantaneous speed on Multi-Channel Scanning Imagery Radiometer,there is a conclusion that the phase error of the original image sequence brought about by the scanning mirror can meet the requirements that the arithmetic of image reconstruction needs to the phase precision.
