Abstract

We consider the results of calculating the point-spread functions (PSF’s) and modulation-transfer functions (MTF’s) in the observation of the earth’s surface from outer space. The PSF’s and MTF’s calculated in the single-scattering approximation are compared with the corresponding functions obtained considering multiple scattering of optical radiation under conditions of varying meteorological range. We give the PSF and MTF calculation results for various wavelengths of optical radiation (0.5, 0.7, and 1.0 μm) and suggest an interpretation of the obtained dependences.
