Electromagnetic wave propagation through realistic inhomogeneous turbulence

Résumé

The Marine Atmospheric Boundary Layer (MABL) is an intricate environment where di- verse atmospheric phenomena can affect electromagnetic (EM) systems. The stochastic multiple phase screen method (sMPS) is conventionally used to model the im- pact of tropospheric turbulence on EM wave propagation. It often relies on the use of homogeneous Kolmogorov spectra. This study presents two original methods for generating inhomogeneous turbulence with sMPS. The LES-Kolmogorov approach uses accurate turbulent struc- ture constant profiles directly extracted from atmospheric simulations, while the Bump-Kolmogorov method (BK- model) approximately replicates it with a parametric model. Log-amplitude profiles computations highlight the specific impact of turbulence inhomogeneity. The proposed methods show good agreements, suggesting the feasibility of an accurate parametric replication of turbu- lence in the MABL.
