1. A system, comprising:
a transmitter node and a receiver node, wherein each node of the transmitter node and the receiver node comprises:
a communications interface including at least one antenna element; and
a controller operatively coupled to the communications interface, the controller including one or more processors, wherein the controller has information of own node velocity and own node orientation;
wherein each node of the transmitter node and the receiver node are in motion relative to each other,
wherein each node of the transmitter node and the receiver node are time synchronized to apply Doppler corrections associated with said node's own motions relative to a common reference frame,
wherein the common reference frame is known to the transmitter node and the receiver node prior to the transmitter node transmitting signals to the receiver node and prior to the receiver node receiving the signals from the transmitter node,
wherein the receiver node is configured to be in a state of reduced emissions.
