Silent Guardian® Protection System
Non-lethal Directed Energy solutions
Raytheon's family of Silent Guardian solutions uses millimeter wave technology to repel individuals without causing injury.
The system's antenna directs a focused beam of energy that travels at the speed of light and penetrates the skin to a depth of 1/64 of an inch, producing an intolerable sensation causing targeted individuals to instinctively flee or take cover. This sensation immediately ceases when an individual moves out of the beam or when the operator discontinues engagement.
Silent Guardian does not cause injury because of the shallow penetration depth of the millimeter wave, and the safety features built into the system. Government tests confirm the technology's safety.
The system provides a zone of protection that saves lives and protects assets on land and at sea. It also provides time to determine intent, stop aggressors and de-escalate violence. Raytheon is developing a family of Silent Guardian solutions.
