A super-resolution imaging technique based on the vortex electromagnetic (EM) wave,
which carries orbital angular momentum (OAM), is reported in this paper. The proof-of-
concept experiment for the EM vortex imaging is conducted. An imaging processing method
based on the real-world OAM radar data is proposed to obtain the target profile.
Experimental results validate the effectiveness of the proposed imaging method and
demonstrate that the vortex EM wave can be exploited to image targets with high-resolution …
