Naumenko V. Methods of increasing the accuracy of frequency-time synchronization in the spaced-out passive radio engineering systems.

Object - the process of synchronization of spatially separated standards of time and frequency in the presence of multi-beam signal of a common source (CS). Aim – to develop methods for improving the accuracy of the spatially spaced standards (standards) of time and frequency in passive radio-synchronization systems under conditions of multi-beam signal of the CS. Subject – passive synchronization method using common source signals in multiposition passive system of synchronization (MPSS). Methods - theories of temporal, spectral and correlation analysis, mathematical modeling of processes, theory of probability and mathematical statistics, numerical analysis in the processing and analysis of simulation results and experimental results. Results – development of a a new method of compensation for the influence of the multi-beam signal of the CS on the resulting error of MPSS synchronization in the spectral region of the analysis; development of a new combined method for improving the accuracy of time-frequency reconciliations in the BPSS; development of a new mathematical model of MPSS, in which, unlike the known models of systems of reconciliation of time and frequency scales, the compensation of multi-beam signal of the CS signal in the spectral region of analysis is realized; development of a new method of synchronization of spatially separated standards of time and frequency measures using low-orbital and mid-orbit artificial Earth satellites. Implemented – the state budget research works, which were implemented in KNURE, as well as in the National Science Center "Institute of Metrology" and the Metrological Center of Military Standards. Application – time and frequency synchronization systems.
