Radar Target Localization by Phased Array with Vortex Wave Generating Elements
Vortex waves (VW) carrying orbital angular momentum (OAM) have azimuth localization property based on phase variation. A phased array (PA) with VW generating elements combine the properties of PA and the vortex array (VA) for angular localization of targets. We have also exploited VW Gaussian beam (GB) generating circular array (CA) in addition to the classical Laguerre-Gaussian (LG) type beams. A rigorous theory of OAM is outlined by the multipole expansion of the spherical vector wave functions (SVWF). Range localization using matched filtering based on SVWF azimuthal mode number (topological charge) is proposed. It is shown that this scheme can be also combined with intrapulse phase coding for a better pulse compression. Two dimensional (2D) angular localization method based on multiple topological charge transmit/receive (TX/RX) patterns is described.
