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.
