radar fire gunfire aimed at a target that is tracked by radar.
radar netting the linking of several radars to a single center to provide integrated target information.
radar picket any ship, aircraft, or vehicle stationed at a distance from the force protected for the purpose of increasing the radar detection range.
radar tracking station a radar facility that tracks moving targets.
radiation intelligence intelligence derived from the electromagnetic emissions of enemy equipment.
radio deception sending false dispatches, using deceptive headings, employing enemy call signs, and so on, over the radio to deceive the enemy.
radio silence a condition in which all or certain radio equipment capable of radiation is kept inoperative.
SIGINT signals intelligence. Personnel and equipment employed in gathering and processing signals intelligence.
