Silent Sentry™
Silent Sentry™, Lockheed Martin's new multi-static surveillance system, utilizes commercial radio and television broadcast signals to detect and track airborne objects. This passive system provides real-time updates on all aircraft within its field of view, up to eight times per second. Because Silent Sentry uses radio signals that exist world-wide, it is a low-cost, low-maintenance, environmentally friendly alternative to conventional radar systems. This unique approach to air surveillance earned the Technology Innovation Award for 1999 from Aviation Week magazine.

The Silent Sentry Technology
Passive Coherent Location technology (PCL) provides Silent Sentry with its detection capability while transmitting no radio frequency (RF) energy. PCL utilizes multiple existing commercial radio and television broadcast signals simultaneously as its source of RF energy.
The continuous wave nature of commercial broadcast signals and the multi-static nature of Silent Sentry enable highly accurate three-dimensional tracking. These characteristics provide inherent benefits to both government civilian agency and military users.
