An Improlved Method For Slant Path Rain Attenuation Prediction

This paper presents a rain attenuation prediction method that uses the complete point rainfall rate cumulative probability distribution as !input data to calculate the attenuation distribution, in an equi-probability basis. The motivation foir this effort was the recognition that the most commonly used prediction method, the one currently recommended by the CCIR, was developed with basis on a limited amount of data measured in temperate climates and offers poor results when applied to sites in tropical and equatorial regions. It was found that some improvement can also be obtained for temperate climates, taking advantage of the larger set of experimental results now available in the CCIR data bank.
