1. An obstacle penetrating dynamic radar imaging system for the detection, tracking, and imaging of an individual or animal located behind an obstruction, the radar imaging system utilizing an arbitrary set of points in space, comprising:

  • more than five low power ultra wideband radar units that include transmitters and receivers, wherein said transmitters produce more than five sets of electro-magnetic signals that emanate from said units and travel through the obstruction to the individual or animal, and produce more than five sets of return radar signals from the individual or animal that travel back through the obstruction to said receivers, and a processing system for said more than five sets of return radar signals for detection, tracking, and imaging of the individual or animal, that includes an array control board, a timing and gain control circuitry that produces real-time video of 30 frames per second for detection, tracking, and imaging of the individual or animal, a delay control board, a gain control board, a transmitter delay control board, an analog to digital converter and amplifier gain board, an image construction board, and a video display monitor, wherein said delay control board, said gain control board, said transmitter delay control board, said analog to digital converter and amplifier gain board, and said image construction board calculate time delays and gains necessary to scan the arbitrary set of points in space and produce information, said information loaded onto said array control board which tells said gain control board and said analog to digital converter and amplifier gain board when to implement the necessary gains and produce a command, wherein said delay control board and said transmitter delay control board receive said command and delay said transmitters and receivers and said gain control board and said analog to digital converter and amplifier gain board apply appropriate gain to said return radar signals for compensation for attenuation through space, and wherein said return radar signals are transmitted to said video display monitor.
