Abstract :
The authors present test results for a number of new applications of RF cable sensors including use on a perimeter fence and laying on different surfaces as a rapid deployment line sensor. This includes the use of RadioGuard on the perimeter of roof tops. An algorithm for solving RadioGuard detects humans moving in proximity to a distributed antenna cable by monitoring disturbances to commercial FM radio signals. By utilizing the transmissions from a number of FM stations and the use of commercial FM radio receiver integrated circuits, RadioGuard provides reliable performance at an affordable price. The unique sensing cable, a modified commercially available TV twin lead, is a key to making this possible. Product design parameters as they relate to both cost and performance are discussed
