MIMO cable guided intrusion detection sensor

In at least one embodiment the present invention relates to a Multiple Input Multiple Output (MIMO) covert terrain following outdoor perimeter security sensor that can detect, locate and categorize intruders as they move in proximity to buried sensor cables. This MIMO cable guided radar utilizes parallel standard leaky coaxial cables with uniform aperture(s) in the outer conductor. RF transmissions from both ends of one cable setup an invisible electromagnetic detection field which couples into parallel receive cables. When an intruder moves within the coupled electromagnetic fields the amplitude and phase of the multiple received signals are altered. Signals received from both ends of each receive cable are processed jointly to detect and locate intruders along the length of the sensor cables. The joint processing of the responses seen from both ends of the cable(s), referred to as End-to-End correlation provides uniform sensitivity along the length of cables without the need for expensive “graded” cables. With multiple receive cables the responses can in turn be used to classify the target in terms of direction, speed and size of the intruder crossing over the cables. The MIMO nature of the present invention can allow one to track intruders crossing the perimeter thereby reducing the number of nuisance and false alarms.
