First Claim
1. An ultra wideband sensor array, comprising:
- a plurality of sensors, each sensor of said plurality of sensors comprising;
an ultra wideband radar; and
an ultra wideband radio, each ultra wideband radio of said plurality of sensors communicating with at least one other ultra wideband radio of said plurality of sensors to synchronize said plurality of sensors; and
a processor, said processor in communication with at least one ultra wideband radio of said plurality of sensors, said processor determining the relative positions of said plurality of sensors based upon ultra wideband position determination techniques, at least two of said plurality of sensors functioning as a bi-static radar.

Abstract
A system and method for highly selective intrusion detection using a sparse array of time modulated ultra wideband (TM-UWB) radars. Two or more TM-UWB radars are arranged in a sparse array around the perimeter of a building. Each TM-UWB radar transmits ultra wideband pulses that illuminate the building and the surrounding area. Signal return data is processed to determine, among other things, whether an alarm condition has been triggered. High resolution radar images are formed that give an accurate picture of the inside of the building and the surrounding area. This image is used to detect motion in a highly selective manner and to track moving objects within the building and the surrounding area. Motion can be distinguished based on criteria appropriate to the environment in which the intrusion detection system operates.
