Benefits of Silent Sentry™

The passive, continuous wave nature of Silent Sentry™, combined with the scalable, expandable architecture, provides many benefits in government civilian agency and military applications. 

The shape of the Silent Sentry volume of coverage.

• Low system cost due to the COTS-based architecture and the use of highly reliable, existing, commercial radio and television broadcast signals.  There is no expense of purchasing and maintaining transmitters.  
• More accurate and more frequent data updates from continuous wave radio transmissions than from conventional radar pulsed transmissions.
• Three-dimensional trajectories are computed with multi-static illumination. 
• Real-time tracking is possible due to the high power of commercial processors. 
• Passive systems transmit no radio frequency energy, are undetectable, and are environmentally friendly. 
• Excellent illumination of low-flying objects is possible since radio and television stations broadcast close to the ground.
• Effective all-weather operation since the low frequencies of commercial radio and television broadcasts are unaffected by weather.
