Patent ID: 7782251

Claim:
A short range mobile millimeter wave imaging radar system comprising: A) a vehicle, B) a frequency scanned millimeter wave imaging radar system mounted on the vehicle, said radar system adapted to detect a plurality of targets located on a relatively flat surface such as airport runways comprising: a) electronics adapted to produce millimeter wave radiation continuously scanned over a frequency range of a few gigahertz in the frequency range between 60 GHz and 100 GHz, b) a frequency scanned transmit antenna adapted: i) to produce a narrow scanned transmit beam in a first scanned direction defining a narrow approximately one dimensional electronically scanned field of view corresponding to the scanned millimeter wave frequencies, and ii) to be mechanically pivoted or scanned in a second direction perpendicular to the first scanned direction so as to define a two-dimensional field of view, c) a frequency scanned receive antenna co-located or approximately co-located with said transmit antenna and adapted to produce a narrow scanned receive beam in a first scanned direction defining a narrow approximately one dimensional electronically scanned field of view approximately co-directed in the same directions as the transmitted beam in approximately the same one dimensional and two dimensional fields of view as the transmit antenna, d) electronics adapted to detect millimeter wave radiation collected by the frequency scanned receive antenna, e) a display monitor and f) computer processor equipment adapted determine location of the targets based on millimeter wave radiation reflected from the targets in the two dimensional fields of view and collected by said receive antenna and to display the location of the targets on the display monitor in a map format.
