Directional enhancements for mobile ad hoc networks (MANET) via doppler null scanning (DNS)

A system, comprising:

• at least two nodes including a transmitter (Tx) node and a receiver (Rx) node, wherein each node comprises:
• a communications interface including at least one omnidirectional 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 is in motion relative to each other and to a common reference frame;
• wherein each node is time synchronized to apply Doppler corrections associated with the motion of said node relative to the common reference frame;
• wherein the common reference frame is known to each node prior to the Tx node transmitting signals to the Rx node and prior to the Rx node receiving the signals from the Tx node;
• wherein at least the Rx node is configured to:
• receive at least one first control message transmitted by the Tx node, the first control message associated with a directional communications link from the Tx node to the Rx node;
• determine a bearing from the Rx node to the Tx node based on one or more Doppler corrections associated with the first control message;
• establish a directional communication link to the Tx node based on the determined bearing;
• and
• transmit at least one second control message in response to the received first control message.
