Paper Abstract

Electromagnetic (EM) vortex carrying Orbital Angular Momentum (OAM) has received more attention recently due to infinite degree of information modulation and unique methods of information acquisition. This paper clarified multi- OAM generation method and introduced a novel radar imaging theory to improve azimuthal resolution by utilizing abundant OAM modes. Subsequently radiated characteristics were analyzed with EM software simulation and numerical simulation to evaluate the potential of EM vortex imaging. The results show that phase distribution and OAM purity in main lobe can satisfy imaging performance. Incoherent pattern direction problem and side lobe energy depressing can be solved by adjusting the radius of concentric uniform circular array.
