Description of the preliminary measurements carried out on the 11 GHz experimental facility at Roma-Monte S. Pancrazio

A microwave data transmission facility is described and test results are given. The radio link is modulated in 4PSK at 140 Mbit/sec. Pluviometers were installed to relate signal depolarization and attenuation to rain events. A data acquisition system was implemented by a 16 bit minicomputer (HP1000/E) with 128 Kbytes RAM memory, a disk of 20 Mbyte and read-write magnetic tape. A block diagram of the data flow of the acquisition program is included. A simulation study covered multipath transmission with an echo. The results of the experiments show that the computerized acquisition system detects events which compare satisfactorily with those recorded in the chart system.
