Analysis of the Ability of Anti-Interference of OAM Radar Beam

Vortex beams are a new type of electromagnetic wave, carrying orbital angular momentum (OAM), with a spiral phase structure, and its demodulation method is different from plane waves. Thus, OAM beams own the ability of anti-deceptive jamming. In this paper, the interference model is built, and whole aperture sampling reception (WASR) is utilized to receive the waveform. Furthermore, the mode distributions are simulated in two cases with and without interference, respectively, to validate the superior capability of anti-interference. The analysis is expected to provide a reference for radar design.
