A New Device for Two-Way Time-Frequency Real-Time Synchronization

The netted wireless sensor nodes or coherent accumulation processing in multistatic radar imaging requires high accuracy time synchronization. Although GNSS timing can also be used as a time synchronization method to serve the applications above, its timing accuracy will be limited. In this context, we present the hardware implementation for Two-Way Time-Frequency Real-Time Synchronization (TWTFRTS) with an automatic adaptive jitter elimination A short (2 km) baseline TWTFRTS experiment was done with a pair of devices composed of a master device and sigma) better than 1 ns.
