Abstract：In order to investigate the intensity scintillation characteristics of a partially coherent radially polarized ring Airy vortex beam(PCRPRAVB)in anisotropic turbulence,the propagation characteristics are investigated by using the step-by-step phase screen method.The results show that as the propagation distance increases,the scintillation index first increases gradually and then decreases when it reaches the maximum value.When the transmission distance is fixed,the scintillation index increases with the in-crease of coherence length.As the truncation factor decreases and the topological charge increases,the scintillation index decreases.The ability of the PCRPRAVB to maintain polarization state is enhanced with the increase of coherence length and topological charge.
