A Novel Vortex Synthetic Aperture Radar Imaging System: Decreasing the Pulse Repetition Frequency Without Increasing the Antenna Aperture

本文提出了一种发射平面电磁波，接收不同模态涡旋电磁波的 SAR 成像系统。基于传统相控阵原理，在合适的参数设计下，涡旋电磁波沿方位向相位历程可近似为线性的，这样相当于在雷达运动方向存在一个虚拟接收天线。当调整不同模态涡旋电磁波进行接收时，可以在雷达运动方形存在一系列虚拟子通道接收，这与方位向实孔径多通道系统类似，因此可以降低 SAR 脉冲重复频率，降低系统设计难度。仿真结果证明了该系统的有效性和局限性。[pdf, SCI, EI, IF=8.1996, CAS-G1 Top, JCR-Q1]
