We present a new beam wander model valid in all irradiance fluctuation regions by using extended Rytov theory with large-scale and small-scale filters. Comparing the calculated results of our wander model and commonly used models with the experimental data obtained in the case of different propagation distances, the waist radius of a beam wave, the outer scale of turbulence and turbulence strength, our new theory gives better agreement with the experimental results than others do.
