Patent ID: 7948428

Claim:
A millimeter wave imaging system comprising: 1) at least one millimeter wave frequency scanning antenna for collecting millimeter wave radiation emanating from a one-dimensional field of view; 2) millimeter wave amplifier components for amplifying at millimeter wave radiation collected by said frequency scanning antenna to produce amplified signals, 3) a beam-former for separating said amplified signals into frequency dependent signals corresponding to frequency dependent millimeter wave beams from said narrow one-dimensional field of view, said beam-former comprising: 1) a plurality of delay lines, 2) a millimeter wave lens, and 3) a plurality of millimeter wave power detectors; 4) a sampling circuit for reading out frequency dependent signals to produce a one-dimensional image of the antenna field of view, and 5) an adjustable focusing means for focusing said frequency-scanning antenna to restrict said one-dimensional field of view to a narrow one-dimensional field of view at a target distance.
