Abstract
This method can be used either as an independent radar system or as an adct to an existing radar system, after suitably modifying the existing system, and will provide a cooperative, Radio Frequency passive, identification system for either stationary or moving targets. The system uses suitable devices that will mechanically vibrate as a transponder mechanism as an attachment to stationary or moving targets. A sideband analyzer is used to identify the viberation pattern in the radar return, and therefore, identifies the target.
