On the space-frequency equivalence of a correlator interferometer


  • G. W. Swenson, Jr.,

  • N. C. Mathur


It is shown that an exact equivalence exists between a monochromatic correlator interferometer using directional antennas and a wideband correlator interferometer using isotropic antennas. The necessary relationship between the frequency response function of the receiving system and the aperture illumination of the antennas to achieve the equivalence is derived.
