Multi-array coherent rf timestamping and phase alignment with run-time clock phase error correction

Abstract

A method includes receiving a data waveform containing a network time signal embedded in the data waveform and recovering a recovered network time signal from the data waveform. The method also includes applying a first correction to the recovered network time signal to obtain a first corrected time signal. The first correction adjusts for deterministic latency associated with receiving and recovering the network time signal from the data waveform. The method further includes providing the first corrected time signal to a clock module and a phase comparator. The method further includes comparing, by the phase comparator, the first corrected time signal as output from the clock module against the recovered network time signal to obtain a local correction value. The local correction value adjusts for latency within the clock module. In addition, the method includes applying the local correction value to obtain a corrected recovered clock signal and outputting the corrected recovered clock signal.
