Kostyria O. Development of theory and technology in the multi positional of passive radio systems high-precision time-frequency synchronization

Object - process of synchronization in the passive multiposition radio engineering systems. Aim - the development of the theory and technology of passive radio engineering systems synchronization of time and frequency with the use of common sources, the development of methods for their implementation. Subject - mathematical model of the passive synchronization systems, methods and algorithms of synchronization using signals of common sources of error synchronization. Methods - temporal, spectral and correlation analysis, mathematical modelling and experimental verification of the theoretical findings. Results - theory new passive radio engineering systems synchronization of time and frequency; developed a new passive method for total coverage; obtained new analytical dependences for determination of the synchronization errors; developed a new generalized model of passive radio engineering systems and a new way of comparisons of spatial scales of diversity standards. Implementation - National scientific center „Institute of Metrology”; Metrological center of military standards of the Armed Forces of Ukraine; Kharkov National university of radio electronics. Application - systems of synchronization of time and frequency
