“…However, the research on the AOA variance for a Gaussian wave still needs further discussion. Gao et al [16] proposed a heuristic model of the AOA variance for a Gaussian wave propagation through non-Kolmogorov turbulence, but lacked adequate evidence to ensure the validity of the expressions. Regarded as an increment to the previous literature studies, this paper not only investigates the similar scenario but also conducts simulations for experimental verification.…”

This paper proposes an empirical model of the angle-of-arrival (AOA) variance for a Gaussian wave propagating through the weak non-Kolmogorov turbulence. The proposed model is approximately expressed as the linear weighted average between the AOA variances of the plane and spherical waves. The Monte Carlo method is applied to validate the proposed model. The numerical simulations indicate that, under the geometrical optics approximation, the AOA variance for a Gaussian wave is insensitive to the change of the diffraction parameter and can be closely approximated by a simple linear relationship in the refraction parameter. These two properties ensure the validity of the empirical model.
