Analysis of Cloud Attenuation Effect on Satellite Communication Systems in Southern Nigeria

摘要

This paper analyses the cloud attenuation effects of communication signals at frequencies of 20-50GHz in the southern region of Nigeria. The methodology adopts the modified model for specific attenuation due to cloud postulated by Lorenzo and Capsoni. The values of specific attenuation under the given conditions of cloud cover were computed by using the absorption coefficient of cloud liquid water a_wand not the traditional use of directly compute cloud liquid water content w The chosen locations are Port-Harcourt, Benin and Uyo.
