Abstract
The bistatic radar network uses an incoherent transmitter for determining the presence, locus, motion, and characteristics of scatterers in a predefined space. The incoherent transmitter generates pulses of high frequency energy that vary in frequency and/or phase. The bistatic radar network having an incoherent transmitter uses a scanning beam antenna located at the transmitter to transmit a focused beam of high frequency energy into a predefined space, with the transmitted beam comprising a series of pulses, each pulse in the series of pulses having a varying frequency, phase, pulse origination time and direction of propagation as it is emanated from said antenna. The transmitter also includes apparatus for determining pulse origination data comprising: frequency, phase, pulse origination time and direction of propagation, for each of the pulses in the transmitted beam emanating from the antenna, where the antenna is scanned in a predetermined scan pattern in at least an azimuthal direction. The bistatic network also includes at least one receiver, located at a site remote from the transmitter and includes apparatus for generating pulse component receipt data indicative of receip…
