Abstract

In order to have a better insight of the various fading mechanisms affecting a line-of-sight link, a thorough knowledge of the meteorological perturbation arising in the lower atmosphere is required. Continuous information about micrometeorological parameters of the lower atmosphere can be obtained by acoustic sounding (sodar). In effect, this technique allows continuous location and measurement of the intensity of thermal inhomogeneities of the atmosphere up to a height of about one kilometer and it can be used under clear, cloudy and foggy weather.

Analyse

Si l’on veut prévoir les mécanismes d’évanouissement qui risquent d’affecter une liaison radio électrique, il faut parvenir à une connaissance aussi approfondie que possible des conditions météorologiques qui régnent dans la basse atmosphère. Les sondeurs acoustiques permettent de recueillir de manière continue des données micrométéorologiques par la mesure des inhomogénéités thermiques de l’atmosphère jusqu’à une altitude d’environ 1 km et ils peuvent être utilisés par temps clair, nuageux ou par temps de brouillard.
