One-Way Wireless Clock Transfer For Coherent Distributed Arrays

One-way wireless clock transfer for cohering the emissions of separated radio frequency transmitters is demonstrated in this paper. The clock signal is modulated onto a carrier frequency and transferred from the master node to the slave node over a wireless link. Leveraging recent developments in high-accuracy microwave ranging developed by the authors, the one-way clock transfer method can be used to implement a simple, low-overhead distributed clock alignment method for cohering the emissions of transmitters in coherent distributed arrays.
