The paper describes the configuration of a synchronization link sharing hardware components with the SAR instrument. Such a system is intended for the TanDEM-X mission. The resulting restrictions on the phase synchronization scheme, timing, and accuracy are investigated. The statistical properties of the phase compensation signal are used to derive a figure-of-merit for synchronization performance. The focus is on the influence of the synchronization link RF hardware on the quality of the derived compensation signal. A system model taking the various influence factors into account is described. The system model is parameterized using statistical analysis from measurement data.
