A target identification system includes a target marker for selecting, and directing radiation at, a target, a weapon delivery system, and means for establishing a two-way communication channel between the two by reflection from a selected target. The communication is by infra-red laser and coded information is sent between the target marker and the weapon delivery system to identify the selected target.

Target identification systems

Apparatus for controlling the direction of a beam of optical radiation from, say, a laser, includes two prisms of small apex angle independently rotatable about a common axis. A control circuit is responsive to the actual angular positions of the prisms and to inputs indicating the desired beam position to cause the prisms to be moved to the appropriate positions.
