Abstract :
An experimental wideband radio link at 15 GHz has been set up on a 17.6 km line-of-sight between Rennes and Laille to measure the variations of the propagation medium characteristics (attenuation and group delay versus frequency) due to meteorological effects. For this, a meteorological system was set up at the receiver station to measure the variations of the meteorological parameters. Consequently, the atmospheric index of refraction is obtained. Particular emphasis is placed on the occurrence of multipath fading in clear air caused by low-level layering in the troposphere.<>
