Abstract:
A radar network for determining the presence, locus, motion, and characteristics of scatterers in a predefined space, said radar network comprising:means for transmitting a focused beam of high frequency energy into said predefined space using an antenna, with said transmitted beam comprising a series of pulses, each pulse in said series of pulses having a frequency, phase, pulse origination time and direction of propagation as it is emanated from said antenna wherein said phase in each pulse may vary from other pulses in said series of pulses; means for determining pulse origination data comprising: frequency, phase, pulse origination time and direction of propagation, for each of said pulses in said transmitted beam emanating from said antenna; means for scanning said antenna; at least one receiver, located at a site remote from said transmitting means, for generating pulse component receipt data indicative of receipt of components of said pulses that are contained in said transmitted beam that are reflected from scatterers in said predefined space; and means, responsive to receipt of said pulse origination data and said pulse component receipt data, for generating scatterer location data indicative of presence, locus, motion, and characteristics of said scatterers in said predefined space.
