Abstract
This paper reports the experimental results of radar imaging using radio waves carrying orbital angular momentum (OAM) for the first time. The phased uniform circular array is employed to generate radio waves carrying various OAM modes. The echoes of all modes are measured sequentially in time by a single antenna. The phase distributions of several modes are measured through near-field measurement system. The azimuthal profiles of single and double corner reflectors are reconstructed by Fourier technique and the azimuth resolution is analyzed. Imaging results verify the ability of azimuth resolution without relative motion using OAM modulation.
