Dynamic Two-way time transfer between moving platforms for netted radar applications

Bi- and multistatic radar systems have larger sensitivity when compared to the monostatic configuration however, at the expense of increased system complexity. Because the different parts that compose the resulting radar system are not co-located, a synchronisation method for remote nodes is mandatory. For moving platforms, the synchronisation link requires a clock steering algorithm which tolerates ever-changing baselines as well as a method to measure the relative positioning throughout the time between a transmitter-receiver pair. It is intended to research, develop and build a versatile networked radar system which allow moving nodes to take advantage of the fact that its different nodes may adapt their relative geometry to the convenience of the situation. This paper reviews frequency and time transfer methods, and introduce the problematic associated with a dynamic two-way time transfer.
