The requirement for the adaptability of mathematical models of systems for processing technical information and functionality (SOTIF) of radio electronic means (RES) should be understood as the need to take into account the main features of the RES in the system model, as well as the complexity (a large number of elements, multi-mode, etc.) and a significant difference in elements RES by the nature of the degradation processes occurring in them, manifested in the differences in their probabilistic characteristics of reliability. The mathematical model of SOTIF RES should take into account the fact that, on the one hand, the real properties of the reliability of the RES may change in the process of targeted use under the influence of external factors, and on the other hand, the available information on the reliability of the RES is always incomplete and inaccurate. Therefore, it is necessary that the mathematical model of the system provides for the possibility of entering additional (a posteriori) information and recalculating the previously found optimal terms and volumes of technical impacts. Goal of the work is to form a reflective model of the change in the state of the RES with the features and at the same time the difficulties of the need to use the composition of the distribution laws, including the a priori and empirical (a posteriori) components. An approach is proposed, according to which, as elements of the REM sample, parts of the equipment are distinguished, which are covered by the influence of given preventive operations. The distribution laws of the operating time to failure of the selected elements can be specified by any functions corresponding to increasing (or increasing on average) functions of the failure rates. In the developed model, the empirical component, in turn, includes two components due to structural and parametric failures (structural and parametric components). A mathematical model of the functional reliability of the RES has been developed and the information-significant characteristics of the reliability of the RES have been demonstrated.

To get an objective picture of the state of near-earth space, it is necessary to update the fleet of information tools in a timely manner, which is characterized by the introduction of new tools and the modernization of old tools, while changing the system in stages as the funds are ready. The continuous build-up of the system's assets as they are ready allows us to improve its performance without waiting for all newly introduced and upgraded assets to be ready. To test monitoring systems in conditions of a large number of heterogeneous elements combined in a system to achieve a single goal, an experimental and theoretical method of evaluating effectiveness based on mathematical modeling is used. The essence of this method is to simulate information at the input of programs of the system tools using mathematical models implemented directly on the system tools themselves. In this case, the quality of test trajectories that would allow evaluating the characteristics of radar information tools and the capabilities of monitoring systems is of particular importance. The purpose of the study is to increase the reliability of the results of tests of radar information tools for monitoring space debris by selecting a rational set of trajectory options that allow for the worst possible implementation of the capabilities of radar information tools, taking into account the functioning of each specific radar information tool participating in the tests. Based on the features of the factor space for finding solutions to the problem of forming test trajectories, the algorithm for forming the initial population and the algorithm for generating a new generation should be supplemented with blocks for checking the observability and feasibility of trajectories. The developed method of forming a rational set of variants of test trajectories using genetic algorithms differs from the known ones in that it generates a set of variants of test trajectories optimized from the point of view of obtaining the worst implementations of the capabilities of radar systems during its testing, under conditions of restrictions on the feasibility and observability of trajectories, the application of the methodology allows automating the process of preparing initial data for testing space debris monitoring systems in order to evaluate their characteristics. The application of the developed method allows to obtain the maximum errors in determining the parameters of the trajectory of space debris elements.

Efficiency assessment is an integral part of the stages of development, testing and operation of optoelectronic systems. The lack of a unified methodology for assessing the effectiveness of optoelectronic systems leads to the fact that different assessment methods are used to compare different systems, as a result of which the results obtained are contradictory and do not provide objective data for making appropriate decisions at various stages of the life cycle of optoelectronic systems. One of the ways to solve this problem is the development of an analytical model, which can be the basis for the construction of a unified set of intellectual support for the design and maintenance of optical-electronic systems at all stages of the life cycle. The aim of the study is to form an analytical model for evaluating the effectiveness of optoelectronic systems, in terms of the functions of threshold contrast and modulation transfer. As a result, the analysis of models for evaluating the efficiency of the optoelectronic systems NVL 1975, FLIR92, NVTerm, NVTermIP and NV-IPM was carried out, and the main differences between these models were considered. The functions of the threshold system contrast and the threshold contrast of the human visual system are considered. The effect on the form of the threshold contrast function of the modulation transfer function (frequency-contrast characteristic) of the system and the external environment, as well as space-time noise, is shown. Then, a description is given of the components of the modulation transfer function of the system and the environment: the modulation transfer function of the turbulence of the atmosphere, the transfer function of the motion modulation of the optoelectronic system, the modulation transfer function of the optical system, the detector modulation transfer function; image processing modulation transmission functions. Monitor modulation transfer functions. The main parameters of the modulation transfer function, which are used to estimate the resolution of the optoelectronic system, are considered. Examples of evaluating the resolving power of various optoelectronic systems are given and the effect of smearing caused by the movement of the carrier of the optoelectronic system on the image quality for different values of exposure time is shown. The practical significance lies in the fact that the research results were applied in the development of tactical and technical requirements for optoelectronic systems, in the development of optoelectronic systems at the stages of preliminary and technical design, showed the consistency of the calculation results with the results of using existing systems.
