This report describes the results of tests made on a radio frequency intrusion detection system intended to protect high-value individual resources. These tests, which were designed to determine the RF field characteristics of the system, were carried out using the system in conjunction with a parked B-52 aircraft. The goals of these tests were to establish the validity of the underlying system concept and to observe its performance in a realistic environment. The sensor consists of a length of leaky coaxial cable that acts as a distributed transmitting antenna deployed on the ground around the parked aircraft. A centrally located monopole antenna on the ground beneath the parked aircraft receives the signal that radiates from the leaky coaxial cable. When an intruder crosses the cable sensor, the received signal is modified, producing a change in the quiescent level of the detected signal.
