The authors present a method for determining the modulation transfer function of iconic opticand-electronic systems for remote sensing the Earth, developed to assess their quality during flight tests and propose a specialized digital image processing software package that implements an algorithm for determining the modulation transfer function. The adequacy of the developed method and the functioning of a specialized software complex for processing digital images is confirmed by satisfactory convergence of the analytical system and the aviation multi-functional optical-electronic one derived from the flight testing the functions of the modulation transfer. The features of mathematical modeling iconic optical-electronic systems of the Earth remote sensing during the tests are presented. The authors present the structure of the mathematical model of iconic optoelectronic systems, which reflects the main links that affect the quality of the image formed. The main quality criteria used in practice for evaluating iconic optical-electronic systems using the mathematical model are presented.
