1. A millimeter wave imaging system comprising:

  • 1) at least one millimeter wave frequency scanning antenna for collecting frequency dependent beams of millimeter wave radiation from a narrow one-dimensional field of view;

    2) millimeter wave amplifier components for amplifying at the collected frequencies said millimeter wave radiation;

    3) a beam-former for separating said amplified collected radiation to produce frequency dependent signals corresponding to said frequency dependent beams, said beam-former comprising;

    1) a plurality of delay lines,2) a millimeter wave lens, and3) a plurality of millimeter wave power detectors; and

    4) a sampling circuit for reading out frequency dependent signals to produce a one-dimensional image of the antenna field of view.
