Abstract
The peculiarities of the account of nonlinear inertial processes that arise in the detecting system of the signal detection system, which lead to a decrease in the quality of conducting a communication session with a spacecraft, are investigated. The conditions of coordination of the system of detecting signals with input influences are determined. The construction of trajectory radio systems with complex directional diagrams is realized either through spatial-temporal transformations of fields of useful signals (and obstacles) leading to the construction of trajectory radio systems with diagramming schemes, or by spatial-temporal transformations of signals in the opening of an antenna lattice, leading to the construction of trajectory radio systems without diagrammaking schemes. In this case, in some cases, the expressions for directional patterns and amplitude-phase distributions are realized by new circuit decisions, which are characterized by higher qualitative parameters compared with known schemes. In comparison with other existing methods, the least number of flaws has a functional method, which is one of the perspective directions in the theory of nonlinear radio engineering systems. In order to assess the impedance of detection of ultrahigh and ultrahigh-frequency radio signals of the radio engineering system of the ground-based automated control system of spacecrafts, it is necessary to take into account the influence of non-linear processes in the detecting device on the quality of reception of information messages. For this, first of all, it is necessary to analyze the nonlinear distortions of information signals in multi-stage signal detection systems.
