Remote phase synchronization for satellite network systems

Remote, distance-independent phase synchronization is a challenging technology for satellite network systems, especially spaceborne bi- and multi-static SAR systems. In this paper, we focus on the theoretical description, performance analysis and experimental verification of a remote phase synchronization system implemented with spatially distributed phase loops. The derivation, simulation and experimental results show that such a system is robust when the relative movement between remote microwave systems has a constant velocity. The proposed approach can also be potentially used in multi-static satellite systems with predictable movements.
