A Systematic Comparison of Near-Field Beamforming and Fourier-Based Backward-Wave Holographic Imaging
In this paper we show the equivalence of near-field beamforming and backward-wave reconstruction algorithm. The proof is carried out analytically with two different approaches, using the principle of stationary phase from a signal processing point of view and the angular spectrum representation as a...
