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.

Systems, apparatus and methods are provided for measuring moving vehicle information. Moving vehicle information may be measured by a sensor configured to respond to one or more wheels of the moving vehicle, where one or more of the wheels change the characteristic impedance of the sensor at the wheel's contact location. An electrical time domain reflectometry signal processing system which is capable of measuring the change in the impedance of the sensor and converting the impedance change to a signal may be connected operatively to the sensor. A data-processing system receives the signal and extracts the moving vehicle information therefrom.

A cybersecurity monitoring device includes an electromagnetic (EM) field sensor for sensing a modulated signal transmitted on an electrical cable which encodes information by varying properties of a periodic waveform. The cybersecurity monitoring device includes a processor and a memory storing a data decoding program including protocol information for identifying a plurality of different communication protocols. The cybersecurity monitoring device is adapted for use without electrical contact in proximity to the cable so that the EM field sensor detects an EM field emanating from the modulated. The data decoding program responsive to detecting the EM field performs signal conditioning including digitizing the sensed modulated signal to provide a digitized signal, decoding the digitized signal using the protocol information used by the modulated signal to generate a decoded signal data, and reporting the decoded signal data or tampering determined from the decoded signal data to a remotely located device or system.
