    • Mot et NBF også under vann - noen muliggjørende sensor- og kommunikasjonsteknologier - teknologiinnspill til FS 07 

      Knudsen, Tor; Lødøen, Stig E. (2006)
      Network centric warfare has proven itself as one of the most important development military developments in recent years. It is now being introduced in more and more land- and air- equipments and systems. Underwater the ...

    • Rumble final report (DE 19) 

      Jenserud, Trond; Knudsen, Tor (2004)
      The main goal of project RUMBLE has been to enhance our capability to predict active sonar detection ranges in shallow water. The idea is to measure ‘through-the-sensor’ the seabed characteristics that affects long-range ...

    • Rumble measurement strategy 

      Dombestein, Elin; Knudsen, Tor (2002)
      This note is one of the deliverables of the RUMBLE program, which aims at developing methods for using operational sonars for measuring and estimating bottom parameters. These parameters are necessary for predicting ...

    • Sensitivity to changes in sound speed on passive bearing and range estimation 

      Knudsen, Tor; Jensen, Jan Kristian (2003)
      A passive towed array can easily measure the bearing to a target. Range can be found by at least two methods; measurements of time of arrival differences at three spaced hydrophone or hydrophone clusters or triangulation ...
