Abstract
A Search and Rescue (SAR) system is disclosed. The SAR system may include a receiver or transmitter node. The receiver or transmitter node may include a communications interface with at least one antenna element and a controller. The controller may include one or more processors and have information of own node velocity and own node orientation relative to a common reference frame. The receiver or transmitter node may be time synchronized to apply Doppler corrections associated with the receiver or transmitter node's own motions relative to the common reference frame. For example, the transmitter node may serve as an emergency locator beacon and mark a location of interest, and the receiver node may determine the marked location of interest based at least on the Doppler corrections.
