Results of the Propagation Measurements Over a 5120 m Link Over Land at 94 GHz (Resultaten van de Propagatiemetingen op 94 GHz over een 5120 Meter Lange Verbinding Over Land).

摘要

In 1983 a 94 GHz propagation experiment was carried out during a period of 6 months over a line of side link from Den Haag to Leidschendam. This experiment was perform to verify the theoretical models of S.H.Lin and to verify the results of a study done by Buijs, concerning the models of Lin for higher frequencies. The models of Lin can be used to calculate the lognormal distribution of rain rate and attenuation, using the data of only one rain-rate meter placed near the transmitter or the receiver with an 'infinitely' long link. This model was not yet tested for high frequencies, like 94 GHz. Although during this experiment the weather in the Netherlands was not very characteristic, due to much rainfall, the models of Lin corresponded very well with the experimental results. The theoretical results of Buijs did not meet the measured for several reasons, the most important being the bad weather of that time.
