Patent ID: 8362948

Claim:
A long range millimeter wave imaging radar system for imaging objects located on regions of an approximately flat surface said system comprising: A) a frequency scanned millimeter wave surface imaging radar system comprising: 1) production electronics adapted to produce millimeter wave radiation scanned over a frequency range of a few gigahertz, 2) a frequency scanned antenna system adapted: a) to transmit millimeter wave radiation produced by said electronics in 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 frequency range, and b) 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 of a surface region, 3) detection electronics adapted to detect millimeter wave radiation transmitted through said frequency scanned antenna system, reflected from objects in said two-dimensional field of view and collected by the frequency scanned antenna system, and 4) computer processor equipment adapted determine location of objects located on the surface regions based on millimeter wave radiation reflected from the objects and collected by said receive antenna.
