    • Beamforming of synthetic target signal acquired by the Atlantis PCL system 

      Strøm, Kyrre; Finden, Erlend; Schell, Jochen; Norheim-Næss, Idar; Lie-Svendsen, Øystein (2016-09-20)
      The passive coherent location system, Atlantis, is a test bed for digital beamforming at the Norwegian Defence Research Establishment (FFI). The system has functionality for real time direction of arrival (DoA) estimation. ...

    • DETOUR trials: The mission and its results 

      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 ...

    • DSI Suppression with Adaptive Beamforming in DVB-T Passive Radar Measurements 

      Strøm, Kyrre; Lie-Svendsen, Øystein; Norheim-Næss, Idar; Johnsen, Terje; Finden, Erlend; Olsen, Karl Erik (2018)
      Adaptive beamforming (ABF) for maximizing the signal to interference plus noise ratio (SINR) is applied to acquisitions made by a passive bistatic radar (PBR) exposed to strong direct signal interference (DSI). The DVB-T ...

    • DVB-T Passive Radar Dual Polarization Measurements in the Presence of Strong Direct Signal Interference 

      Strøm, Kyrre; Lie-Svendsen, Øystein; Finden, Erlend; Norheim-Næss, Idar; Johnsen, Terje; Baruzzi, Aurora (2017)
      A dual-polarization passive bistatic radar is used to evaluate the potential benefit of cross-polarized measurements for the suppression of strong direct signal interference in the DVB-T band. The linear array antenna ...

    • Passive Radar detection of small UAV over sea 

      Norheim-Næss, Idar; Finden, Erlend; Strøm, Kyrre (2019-07-22)
      During a trial over the Trondheim-fjord in Norway fall 2018, aDVB-T based passive radar system was used for detecting a small unmanned aerial vehicle (UAV) over sea. The measurements show a possible detection range of 1 ...

    • VErsatile RAdar – RFSoC based radar demonstrator for multiple applications 

      Norheim-Næss, Idar; Christiansen, Jonas Myhre; Buskenes, Jo Inge (2022-10-04)
      The Norwegian Defence Research Establishment (FFI) VeRa (Versatile Radar) is a radar demonstrator for multiple applications based on the 1st generation Xilinx RF System on Chip (RFSoC). This paper describes the hardware ...
