Abstract: Compared with classical electromagnetic (EM) waves, the vortex electromagnetic wave carrying orbital angular momentum (OAM) has higher dimensional information-modulation freedom, which paves the way to the OAM's applications in radar target detection and imaging. Firstly, the concept of vortex EM wave and the radiation field in linear polarization are introduced. Subsequently, the principles of the vortex-EM-wave-based radar imaging and detection are presented. The advantages over traditional radar detection technology are analyzed and elaborated. Moreover, the development history and research actuality of the EM vortex imaging and the rotational Doppler frequency detection are overviewed. Especially, the generation technique of vortex EM waves for radar detection purposes is summarized. Finally, by viewing the prospects for the applications of vortex EM waves, some scientific problems in the development of vortex-EM-wave-based radar are proposed.

Key words: vortex electromagnetic wave, orbital angular momentum, novel radar paradigm, electromagnetic vortex imaging, rotational Doppler detection
