Parabolic-equation based study of atmospheric turbulent effects on evaporation duct radio wave propagation

Abstract

Evaporation duct is an imporatn factor affecting the near sea surface radio wave propgation. Based on the atmospheric boundary turbulence theory and the parabolic wave equation, the propagation model considing the randomized refractivity is proposed. The numerical simulation compared the influence of theturbulence the results shaows that accounting for the physical mechanism of the atmosphere turbulence is s an important factor. It can reduce the propagation distance of radar wave propagation and affect the detection probability and range of radar to the tarbet beyond the horizon.
