      Nevstad, Gunnar Ove (2008)
      Studied composition PBXW-11with 30wt.% aluminium class 7 powder is a Norwegian produced explosive equal to the American PBXIH-18 composition. By slightly modification of the aluminium content the studied composition will ...
    • Determination of detonation velocity and pressure for MCX-6100 

      Nevstad, Gunnar Ove (2015-12-02)
      Independent of the application of an explosive composition there are certain properties that are important to know. Performance depends on properties as detonation velocity and detonation pressure. Sensitivity of munitions ...
    • Detonation transfer : summary report, FFI project 803.03 

      Holm, Knut B.; Martinussen, Svein Erlend; Svinsås, Eirik (2003)
      In connection with the upgrade of AMRISK, a program for risk analysis of ammunition storages, the process of detonation transfer have been studied. Based on earlier work a model for sympathetic detonation is developed ...

      Stejskal, Vojtech; Kuschel, Heiner; Brenner, Tateusz; Lamentowski, Leszek; Norheim-Næss, Idar; Samczynski, Piotr; Kulpa, Janusz (2017)
      In this paper DMPAR Evaluation Trials for Operationally Upgraded Radar (DETOUR) and their results for a selected scenario are described. The DETOUR trials were conducted by the SET-195 research task group (RTG) under an ...
    • Development and Calibration of a Low-Cost Radar Testbed Based on the Universal Software Radio Peripheral 

      Christiansen, Jonas Myhre; Smith, Graeme E. (2019-12-01)
      For a cognitive radar algorithm to be useful, it must run on radar hardware that is flexible. Typically, this has been viewed as requiring a software-defined radio. With the emergence of cheap, digital transceiver systems, ...
