Annotation:  The article presents the author's method of synthesis of the modulation transfer function of digital optical-electronic systems during flight tests, developed for assessing the quality of digital optical-electronic systems of remote sensing of the Earth, and describes the architecture of the specialized software complex that implements it. The adequacy of the developed methodology is confirmed by satisfactory convergence of the analytical and derived from the flight tests of the modulation transfer functions of the aviation multi-functional optical-electronic system. Using the quality criterion of digital optical-electronic systems, based on the modulation transfer function, allows you to get maximum information about the transmission properties of this system or an individual link and to make a choice of links and systems based on specific requirements. This allows you to synthesize digital optical-electronic systems of remote sensing of the Earth along individual links, and using the developed method of synthesizing the modulation transfer function, you will ensure that the mathematical model of the digital optical-electronic system is correctly selected during the tests.
