Ground wave attenuation curves in the presence of successive 2-D island

Abstract

Numerical solutions are presented for the formulation given by Furutsu in calculating the transmission loss of HF ground wave radar/communication systems in the presence of successive 2-D islands aligned along the propagation path. The curves for the variation of the ground wave attenuation factor with the operation frequency and the number and the size of the 2-D canonical island models yield us important hints about the total transmission loss one should expect in the design of HF ground wave radar/communication systems.
