Measurement of the rotational Doppler frequency shift of a spinning object using a radio frequency orbital angular momentum beam.
TL;DR: An indirect approach based on phase measurement is proposed to measure the rotational Doppler frequency shift, which takes full advantage of the phase structure of orbital angular momentum (OAM) beams in radio domain, using a vector network analyzer (VNA) as a phase discriminator.
