Cooperative passive identification system for moving or stationary objects

摘要

This method can be used either as an independent radar system or as an adjunct 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.
