Fence Detection System.

This report culminates the efforts for the development of a fence detection system using the Magnetic Integrated Line MILES or Enclosed Wire-in-Tube EWIT Transducers. The effort consisted of collecting analog data from transducer samples mounted to a chain link fence at Rome Air Development Center Site 2D, Rome, NY and analyzing this data, in addition to MERADCOM furnished data, for the purpose of developing a computer model of a signal processor for intrusion detection. Design goals for the processor included a probability of detection of at least 90 and a nuisance alarm rate of less than 1 in 48 hours under a variety of manmade and environmental disturbances. Detection criteria included fence climbovers with the assistance of a ladder, intruder climbing to the top and jumping off, fence climbovers using carpeting as protection against the barbed tape and cutting the fence. Nuisance alarm rejection is based on input stimuli to include thunder and lightning within a 5 mile radius, wind speeds to 36 mph, power line induced signals and large vehicles greater than 20 meters away.
