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

<p>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 synchronization method to serve the applications above, its will limited. In this context, we present hardware implementation for Two-Way Time-Frequency Real-Time Synchronization (TWTFRTS) with an automatic adaptive jitter elimination algorithm based on Kalman and PID, which is implemented real-time, low-cost, portable Xilinx ZYNQ device. A short (2 km) baseline TWTFRTS experiment was done pair of devices composed master device slave The result shows precision performance standard deviation (1 σ) better than 1 ns.</p> <p> </p>
