Power Spectrum Analysis on the Image Quality of FA-2 & GMS-5 IR Channels

The image qualities of FY-2 and GMS-5 IR channels are analyzed by means of the image power spectrum analysis. The results show that the sum of the components in the image power spectra of FY-2 IR channel is a little less than that of GMS-5 IR A channel, and based on the results of numerical simulation experiment, it is shown that the image quality of FY-2 IR channel is equivalent to that of GMS-5 IR A channel.
