Abstract:

An imaging millimeter wave radar system. The system includes a millimeter wave transmitter transmitting a frequency scanned millimeter beam that is narrow in the scanned direction and wide in a direction perpendicular to the scanned direction. The system includes a receive antenna and a Rotman type lens for forming a one-dimensional image in the perpendicular direction of targets in the antennas field of view based on millimeter wave radiation reflected from the targets. A computer creates a two dimensional image based on the scanning direction of the transmit beam of the transmit antenna and the one dimensional image from the receive antenna. Distance to the target is determined based on difference in frequency of the transmit signal and the receive signal. Thus, a three dimensional view of the systems field of view is determined by the system. This view can be displayed on a monitor using color to represent target distance.
