In this study, we conduct a thorough investigation into the focusing transmission characteristics of scalar and vector beams in atmospheric turbulence by combining theoretical derivations with angular spectrum simulations. We compare the focusing performance of typical scalar beams (Gaussian beam) and vector beams (lemon vector beam and radially polarized vector beam) under weak and strong turbulent conditions. Our research reveals that, whether it is in weak or strong turbulent conditions, the focused Gaussian beam exhibits the highest average peak power density and the smallest radius of 63.2% encircled energy at the focal plane. However, its scintillation index significantly exceeds that of the focused lemon vector beam.
