From http://www.dtic.mil/ndia/jaws/sentry.pdf The heart of Silent Sentry is its innovative Passive Coherent Location (PCL) technology developed by Lockheed Martin Mission Systems, which uses everyday broadcast signals, such as those for television and radio, to illuminate, detect and track objects. Just like the celldar system from Roke Manor then... cheers A passive detection system for U.S. government civil agency and military purposes, Silent Sentry transmits no radio frequency (RF) energy as conventional radar does and has no RF "signature" to alert enemy threats. Instead, it can use the energy that already exists in airspace for detection purposes, and does not adversely affect or harm the environment.
