Abstract :
A system designed to measure the space-time variation of rainfall rate R (mm/h) and specific attenuation Y (dB/km) is presented. The design constraints include a limited budget and a desired capability of capturing realistic propagation conditions expected to occur in millimeter-wave wireless systems with short links operating in a tropical region. The system consists of a disdrometer, a network of rain gauges, and a 29 GHz transmitter-receiver set, all to operate in a small campus area. The rain gauges will measure the distribution and space-time variation of rain rate. The disdrometer will measure drop size distributions necessary to derive the power-law coefficients for R-to-Y conversion, to be verified against measurements of attenuation on the 29 GHz link.
