1. An apparatus for superresolution imaging of a remote target, the apparatus comprising:

  • a receiver having a predefined receiving aperture for capturing an image of the target;

    a plurality of transmitters spaced apart from one another and configured to concurrently emit signals directed toward the target with a phase difference therebetween, wherein the plurality of transmitters are further configured to emit overlapping beams onto the target such that interaction of the overlapping beams with the target produces a fringe pattern modulated at spatial frequencies beyond a resolution limit of the receiving aperture; and

    a processor configured to process the image including at least a portion of the fringe pattern in order to produce a superresolved image including spatial frequency content beyond the resolution limit of the receiving aperture.
