Paper Abstract

A measurement system for the observation of the influences of the local climate on the transmission behaviour at millimeter waves has been developed and tested. Because of the required high resolution for path attenuation changes the coherent measurement principle has been selected, thereby simultaneosly avoiding a biologically relevant power density anywhere in the open transmission path. Both transmitter and receiver antennae have been placed at the same end of the bidirectional transmission path to facilitate the coherent measurement, whereas the other end consists of a metallic reflector.
