Rain Attenuation Studies
Abstract
The statistical properties of rain attenuation which dominate propogation at frequencies above 10 GHz are required for planning radio systems at these frequencies. These properties are studied for three frequencies, 11.2, 12.7 and 18.76 GHz and various link lengths, 2.5, 5, 7.5, 10, 12.5 and 15 mi at six locations in Canada. Two approaches were used to simulate the attenuation; one utilizes weather radar data in the AZLOR format, a rectangular coordinate variation of PPI; the other utilizes rainguage records and radiosonde data and the concept of a synthetic storm. Rain attenuation statisitcs are developed from these two approaches to describe the probability of occurence of an attenuation event for single links of various length, pairs of parallel links with various separation distance and for pairs of links on the same route.
