X-Band Radar for Simultaneous Multiple Target Localization Based on Collimated Vortex Waves

Abstract

Electromagnetic vortex waves (VW) generated by a uniform circular array (UCA) are tightly collimated by a paraboloidal reflector into a radiation cone with a small vertex angle and beam-width. This antenna system is used in a conceptual design of a medium range X-band high resolution radar sensor for localization of multiple targets simultaneously. Its features, including the performance with clutter and ground multipath, are comprehensively analyzed yielding novel results. The VW based algorithms for range and angular localizations of multiple targets are given. The effects of the tolerances of the UCA element excitations are estimated. Results for Monte Carlo simulations for localizations and detection performance are presented.
