Three-Dimensional Imaging Method of Vortex Electromagnetic Wave Using MIMO Array

The traditional multiple-input multiple-output (MIMO) linear array of inverse synthetic aperture radar (ISAR) need to scan in height dimension in order to get the three-dimensional imaging of the target in the near field. In this paper, based on vortex electromagnetic wave MIMO linear array, a method is proposed for ISAR radar three-dimensional imaging, and the principle is designed for the radius of uniform circular array (UCA). Simulation results indicate that the proposed method can accomplish three-dimensional imaging of the target.
