Comparison of the diffraction stack and time-reversal imaging algorithms applied to short-range UWB scattering data

Comparison of different techniques for short-range UWB radar imaging has been performed based on experimental data. To acquire experimental data, a video-impulse radar with a specially developed antenna system with a single transmitter antenna and an array of receiver antennas has been used. Topology of the receiver array was made in such a way that the footprint of the receiver array does not have any sidelobes.
