Further applications of the substitute-sources method
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2004

A substitute-sources method (SSM) was developed and tested for sound propagation in a turbulent atmosphere, including upward refraction [1]. In the present paper a situation with turbulence and a non-flat terrain is studied. A comparison with the results from a parabolic equation method (PE) shows good agreement.
