Paper Abstract

We present a method for three-dimensional scene reconstruction in the millimeter-wave part of the electromagnetic spectrum. The millimeter waves captured by sparsely distributed antennas are up-converted to optical domain using electro-optic phase modulators. The modulation is a coherent process in that it preserves the phase information carried by the millimeter waves and encodes it in the phase of the optical carrier. In the optical domain, the signal is then transmitted using optical fibers to an optical cross-correlation engine where all pair-wise cross-correlation terms are measured. The 3D millimeter-wave representation of the scene is then reconstructed digitally from those crosscorrelation terms.
