"DUCT TALK" RADIOMETEOROLOGY, TROPOSPHERIC DUCTING AND ITS IMPACT ON WANTED AND UNWANTED SIGNALS - Dr Andrew ('Andy') Kulessa Colloquium
Ever wondered how the weather impacts on the propagation of terrestrial radiowaves? Why 50cm broadcast transmitters can interfere with radioastronomical observations for long periods of time, despite being located hundreds of kilometres away and way beyond the local horizon? Whether such ducting events can be reliably predicted?. These questions are of wider interest, for scientists, engineers and technologists designing wireless communication services, managing spectrum & RFI and conducting radio-astronomical observations eg. ISM researchers may find considerable analytical synergies!
