Abstract
An electronic identification system for use by vehicles on a battlefield comprises an interrogator circuit in an attack vehicle and a transponder circuit in several other vehicles which are friendly but could be mistaken for the enemy. In operation, the interrogator circuit transmits a time shifted code which is very difficult for an actual enemy to detect and/or jam, and which causes the transponder circuits to send a response from only a selected one of the other friendly vehicles that is being examined by the attack vehicle as a target.
