“…In the last decades, several synchronization techniques for distributed radio systems have been proposed. In 1968, Thompson et al [2] discussed, compared and classified the available techniques for reducing propagation induced phase fluctuations in frequency distribution systems and defined the principle of round trip stabilization systems. This work was developed under the context of very long baseline arrays for radio astronomy applications.…”

“…Those applications can be seen as distributed radio systems, however, the distributed nodes have a fixed position and the synchronization and signal distribution is done usually by means of an auxiliary wired or wireless transmission media. The phase synchronization schemes described in [2] can be generalized as distributed Phase Locked Loops (PLL). In those distributed PLLs, a direct feedback action is applied over a two-way transmission media as part of a whole phase loop under the assumption of channel reciprocity.…”

Phase, frequency and time synchronization is a crucial requirement for many applications as such as multi-static remote sensing and distributed beamforming for communications. The literature on the field is very wide, and in some cases, the requirements of the proposed synchronization solution may surpass the ones set by the application itself. Moreover, the synchronization solution becomes even more challenging when the nodes are flying or hovering on aerial or space platforms. In this work, we compare and classify the synchronization technologies available in the literature according to a common proposed framework, and we discuss the considerations of an implementation for distributed remote sensing applications. The general framework considered is based on a distributed collection of autonomous nodes that try to synchronize their clocks with a common reference. Moreover, they can be classified in non-overlapping, adjacent and overlapping frequency band scenarios.

These works were usually applied to very long baseline arrays for radio astronomy applications.…”
