ABSTRACT:
A ported coaxial cable is positioned within a coil of barbed wire and is coextensive therewith. Radio frequency energy applied to the cable is confined within the tubular volume of the coil. Variations in the reflected energy caused by physical disturbances of the coil are processed by detection system signal processing equipment to determine the incidence and location of intrusion events.
