1. A method comprising:
detecting radio frequency energy without phase detection at all pixels in a beamspace of one or more lenses;
digitizing, with parallel processing of a two-dimensional array, the detected radio frequency energy in the beamspace of the one or more lenses; and
generating one or more images based upon the digitized radio frequency energy in the beamspace of the one or more lenses.
