Abstract
Recently, electromagnetic (EM) vortex with orbital angular momentum (OAM) attracts more attention in radar imaging fields, which needs a variety of OAM modes. However, most of them are based on motion relative static. In this paper, we propose a novel SAR imaging method based on electromagnetic vortex with OAM. The geometry model of synthetic aperture radar (SAR) is utilized for EM vortex with OAM and the echo signal model is deduced correspondingly, including the additional phase items produced by EM vortex waves. Then the imaging algorithm aiming at OAM based on Chirp-Scaling algorithm is proposed. Simulation results validate the effectiveness of the proposed method and that OAM beams can be applied in SAR signal processing.
