METHOD OF TELEMETERING SIGNAL RECORDING AND PROCESSING WITH TIME CHANNELING Russian patent published in 2008 - IPC G08C15/06 G06F17/40 

FIELD: measuring equipment.

SUBSTANCE: method consists, that beep signal radiotelemetering signal is received, transformed, recorded and analysed. Transformation stage implies formation of instantaneous quadrature components of telemetering signal at intermediate frequency. Obtained data is digitised. Analysis stage includes restoration of temporal pattern of group telemetering signal. Thus within each interval corresponding to a priori known telemetering signal cycle duration, for resulted quadrature components and resulted clock signal, cross-correlation function is calculated. Then cross-correlation function is calculated. Specified range is used to form arrays corresponding to separate cycles of telemetering signal. Within V cycles duration interval arrays are summed. Maximal total function indicates cycle phase. Based on cycle phase and a priori known telemetering signal pattern, arrays corresponding to resultant separate discrete messages of group telemetering signal are formed.

EFFECT: reduced telemetry losses associated with real-time synchronisation system response time.
