  Institution description
  • Educational and research services in the fields of telecommunications, radio frequency engineering and electromagnetic wave propagation.

  •  
  • Research and Development Activity Areas:

  •  
    - (1) Acoustics and sound engineering,
    - (2) Opto-electronic communications,
    - (3) Radar and microwave propagation research (tropospheric remote sensing).
     
  • The Radar and Propagation Research Group is involved with radar and microwave based instruments.
  • Methods and algorithms developed are being used primarily for the purposes of atmospheric and cloud physical research, snow avalanches, and for practical applications in the fields of (aviation) meteorology and hydrology.

  •  
  • Key activities in this field are:

  •  
    - (a) Development and application of "Avalanche radars" (pulsed C-band Doppler radars) for the xxxxxxdetection and speed profiling of snow and ice avalanches (cooperation with Institute of
    xxxxxxSnow and Avalanche Research, Innsbruck; EU 4th Framework Project "SAME").
    - (b) Design and successful implementation of the Central European Weather Radar Network
    xxxxxx("CERAD") with 10 countries participating (A, CH, CZ, CRO, D, H, I, PL, SLK and SLO);
    xxxxxxCooperation with the Central Institute for Meteorology and Geodynamics, Vienna.
    - (c) Representation of Austria in the European Concerted Action COST-75, "Advanced
    xxxxxxWeather Radar Systems",
    - (d) Representation of Austria in the European Concerted Action COST-76 ("VHF-UHF-
    xxxxxxWindprofilers and Vertical Sounders), development of an experimental 1280-MHz-
    xxxxxxWindprofiler (vertically looking pulsed Doppler radar).
    - (e) Feasibility and definition study for a ground based cloud profiling radar (cooperation with
    xxxxxxJoanneum Research under contract to ESA) for application in atmospheric and climatic
    xxxxxxmonitoring missions (ground truth instrument for spaceborne cloud radars).
    - (f) Development and implementation of high-speed and high-volume multi-channel data
    xxxxxxacquisition systems for radar video signal archiving and analysis.
