Structured Radio Beam for Radar Detection

Abstract

The orbital angular momentum (OAM) carrying beams associated with helical wavefronts can be viewed as a complete set of eigen-modes for the electromagnetic waves, thus can be used to realize the structured radio wavefront with desired intensity and phase distribution. The structured radio beam maintains the vorticity and orthogonality of the OAM modes and has a directional gain. The unique characteristics provided by structured radio beam may afford a new solution to radar detection.
