Comparison of the level of attenuation between a lower integration time and a higher integration time in a tropical location

ABSTRACT

Rainfall is a vital factor that must be considered in the design of telecommunication systems. The challenges posed by rainfall at frequencies above 10 GHz on microwave terrestrial and space communication systems, especially in tropical and equatorial zones, is a major problem for the telecommunication engineer. In recent times, it has been observed that rain that fall within a very short period has more effect on radio signals than rain that occur at a longer period of time. Rain events can last for an extended period of time, but the most significant attenuation due to rain occurs during relatively short periods of very intense rainfall. In this work, 2 –year data collected using vertically-pointing Micro Rain Radar were used to determine and compare the level of attenuation and the result shows that the level of attenuation at lower integration times is more than the one that occur at higher integration times.
