A two steps strategy is presented for phaseless antenna diagnosis. In the first step, an antenna setup derived from Leith-Upatnieks holography with synthesized reference wave is used to retrieve the phase of an amplitude-only measurement. Instead of using a phase shifter to synthesize the phase of the reference wave, a set of mechanical shifts are applied to the probe to produce the same effect. As...
A setup for phaseless microwave imaging is presented in this paper. The setup is based on the Leith-Upatnieks or off-axis holography in which the scattered signal is combined with a reference signal that is known in both amplitude and phase. The reference signal is synthesized by a mechanical movement of the object under test together with the injection of a constant signal. Thus, previous measurement...
