Abstract
An enemy radar or transmitter transmits a signal at frequency f1. A tag on a friendly forces target receives frequency f1 and, in response thereto, transmits a signal at frequency f2≠f1 modulated by a code unique to the tag. A friendly forces receiver, in response to receiving frequency f2 provides an indication that (a) the tag has received frequency f1, meaning the enemy is operating in the area, and (b) which specific tag has received a signal at frequency f1. The friendly forces can then take appropriate action.
