An approach to real-time microwave holographic imaging was studied. In particular, spatially noncoherent wavefront reconstruction methods were evaluated theoretically, numerically, and experimentally. Spatially noncoherent reconstruction is done by doubling holograms; that is by forming two axially symmetric replicas of an original hologram. Axially symmetric pairs of points are coherent but not coherent with other pairs. Two theoretical descriptions of the reconstruction are given. One theory assumes a hologram is formed and computes image intensity of the doubled hologram on the basis or array theory for the region of Fraunhofer diffraction, the farfield. The other theory also computes farfield image intensity, but it describes hologram formation for a point object and references source; this theory involves integration over continuous apertures rather than discrete point sources as in array theory.
