Abstract

A system for detecting weapons is provided. The system includes a radar system transmitting electromagnetic radiation, analyzing reflected signals to detect a weapon, and generating reflected signal data. An energy field parameter system receives the reflected signal data and sets a plurality of energy field parameters. An energy field system transmits energy at a location associated with the detected weapon.
