Computation of Rain Attenuation through Scattering at Microwave and Millimeter Bands in South Africa

摘要：

　　Attenuation due to rain at frequencies above 10 GHz in temperate climates and above 7 GHz in tropical,sub-tropical and equatorial climates is a critical factor for both terrestrial and satellite link system designers.This paper presents results of computed and measured attenuation due to rain,using the spherical method(Mie Scattering technique)and non-spherical method(Pruppacher and Pitter technique).The derived scattering amplitude coefficients are incorporated with available measured rain rate and droplet size distribution data to estimate specific and total attenuation for the region of South Africa.The results are then compared with the few existing rain attenuation models and the one-year attenuation measurement campaign in Durban,South Africa.The results are further applied to the terrestrial radio links and satellite links at a chosen rain rate and specified frequencies.
