The ionosphere is an important part of the earth's atmosphere,which is composed of ion-ized plasma and has important influence on over-the-horizon communication,satellite communica-tion and spacecraft.The incoherent scattering radar is the most advanced equipment for obtaining i-onospheric plasma parameters.At present,incoherent scattering radar uses traditional plane waves for detection,while vortex electromagnetic wave is a new type of electromagnetic beam,and its ap-plication value in incoherent scattering needs to be explored.This paper selects a typical vector Bessel vortex beam,explores its prospect in ionospheric incoherent detection on the basis of rele-vant theories,and points out the possibility detecting plasma motion and ionospheric irregularities by using it.
