DETECTION OR RANGE DETERMINATION OF DISTANT OBJECT BYAPPARATUS USING SENSOR OF ELECTROMAGNETIC OR SOUND ENERGY:
(under the class definition) Subject matter relating to teaching or demonstrating the operation or characteristics of a means for locating, or finding the distance to, a remote object (e.g.., an enemy aircraft, etc.) by use of electromagnetic or sound energy detecting means.
(1) Note. Instruction can be done by any means, actual or simulated; however, when using actual means the input signal representing the remote object is a simulated signal.
