    • Analysis of bottom samples collected from the Norwegian Trench during Rumble Second Sea Trial 

      Jenserud, Trond; Ottesen, Dag (2004)
      The RUMBLE second sea trial was carried out in the Norwgian Trench northwest of Stavanger in September –October 2002. 35 grab samples were collected during the experiment. This report presents the results of grain size ...
    • Analysis of bottom samples from Vestfjorden collected during Rumble First Sea Trial 

      Jenserud, Trond; Ottesen, Dag (2002)
      As a part of the RUMBLE first sea trial 15 sediment samples were taken from two areas in the inner and outer Vestfjorden, respectively. This report presents the results of the analysis of the sediment samples. The seabed ...
    • A collection of oceanographic and geoacoustical data in Vestfjorden - obtained from the MILOC survey Rocky Road 

      Jenserud, Trond (2002)
      A brief overview of oceanographic and geoacoustic data from the Vestfjorden area is given. The overview is based on data collected during the MILOC survey Rocky Road, which took place during 1992-95.
    • 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 project - scattering index models 

      Jenserud, Trond; Simons, Dick; Cristol, Xavier (2001)
      In this note we describe some models for the backscattering strength of a rough seafloor. The models range from the simple Lambert’s rule to perturbation models that include the effect of roughness and volumeinhomogeneities. For ...
    • Summary report on analysis of acoustic data from the SWASI-99 array experiment 

      Eidem, Ellen Johanne; Jenserud, Trond; Søstrand, Knut A.; Tollefsen, Dag (2003)
      The localization of underwater acoustic sources in a shallow water environment is addressed. Two array signal processing methods suitable for low-frequency signals in shallow water have been applied to data from an ...
    • Technical report on assessment of rumble inversion results (DE18) 

      Chalindar, B.; Jenserud, Trond; Knudsen, Tor; Dombestein, Elin; Plaisant, Alain; Ainslie, Michael; Ellingsen, Ingunn (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 ...
    • The Watermark manual and user's guide - version 1.0 

      Walree, Paul van; Otnes, Roald; Jenserud, Trond (2016-11-29)
      Watermark is a benchmark for physical-layer schemes for underwater acoustic communications. It allows researchers and modem manufacturers to develop, test and compare algorithms for the physical layer under highly realistic ...
