Title: Statistical properties of the background noise for the atmospheric windows in the intermediate infrared region
Abstract: The statistical properties of the sky-, forest- and cities-background noise for the four atmospheric windows in the intermediate infrared spectral region (2–14 μm) were analysed. There are the two kinds of spectral regions where the statistical properties about the amplitude distribution of the background radiance are quite different: one is the 2–3 μm region, being dominated by the scattering sunlight, the other is the 8–14 μm region, where the thermal radiation from the background is predominant. In the latter, the background noise is well described by the statistical model based on the random pulse process with the Gaussian amplitude and Poisson's width distribution. In the former, both the amplitude and the width of the random pulse follow the Poisson's statistics. The unified statistical model for the background noise including the whole intermediate infrared spectral region was derived. Its validity was confirmed with some experimental results.
