Research on Propagation Distance and Pattern of Vortex Radar Based on Uniform Circular Antenna Frequency Diverse Array

This paper primarily introduces the vortex wave radar based on a circular frequency diverse antenna (FDA) array and analyzes the research on the propagation distance and patterns of vortex waves generated by the frequency diverse array. Through simulation and modeling of vortex wave patterns, we have successfully analyzed the dependency and variations of vortex beam patterns on propagation distance.
