Abstract
The bistatic radar system 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. The transmitter also includes apparatus for determining pulse origination data comprising: 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 radar system 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 receipt of components of the pulses that are contained in the transmitted beam that are reflected from scatterers in the predefined space. The receivers all transmit their data, substantially instantaneously, as received back to a central processor, which synchronizes (collates) the data in order to calculate, in near real-time, vector wind fields, divergence, vorticity, etc. These calculations typically are performed in polar coordinates or can be performed in Cartesian coo…
