Abstract:
An intrusion detection system comprising:a plurality of ultra wideband (UWB) sensors, said plurality of UWB sensors arranged in a sparse array, wherein at least a first UWB sensor of said plurality of UWB sensors is adapted to transmit UWB pulses, said UWB pulses having a wavelength corresponding to the center frequency of said UWB pulses, and wherein at least a second UWB sensor of said plurality of UWB sensors is adapted to receive signal returns of said transmitted UWB pulses reflecting off an object, said signal returns corresponding to forward scattering data; and a processor in communications with at least said second UWB sensor, wherein said processor distinguishes motion of said object based on a criteria established for the environment in which the intrusion detection system operates and said forward scattering data, and wherein said processor triggers a condition when said object penetrates a boundary.
