Abstract
Based on the extended Huygens-Fresnel principle, universal curves representing signals reflected from a diffuse target, which may contain multiple glints, are calculated for uniform transmitted and local oscillator beams. For a far-field diffuse target, substantial gain on the signal-to-noise ratio may be obtained by increasing the receiver aperture up to three times the transmitter aperture. The receiver heterodyne efficiency for the two beams with slight misalignment is also presented in this paper.
