Abstract
A target electronic system forms part of a marker beacon. The target system ids in detecting the marker beacon upon deployment. A seeking electronic system for locating the target system may be mounted on an air vehicle, land vehicle, sea vehicle, or backpack. The target system, upon deployment of the marker beacon, sends out signals identifying the marker beacon's use, identity, and direction. The seeking system then responds by querying the target system of its distance. The target system then responds to this query. The seeking system then has the option of sending a signal to have the target system initiate the activation of a flare. The activated flare can then be used for visual and infrared detection.
