    • Analysis of detection performance of incoherent range walk compensation for passive radar 

      Finden, Erlend; Christiansen, Jonas Myhre; Lie-Svendsen, Øystein; Olsen, Karl Erik (2015)
      This paper analyzes the performance of an incoherent range walk compensation method for passive radar systems. The method utilizes the velocity information in the range-Doppler map, and no detection before compensation ...
    • Attainment of goals for the Norwegian led provincial reconstruction team in Faryab - an assessment 

      Martinussen, Svein Erlend; Barstad, Andreas; Christiansen, Jonas Myhre (2014-02-11)
      This work addresses the question: “Did we achieve what we planned to do in Faryab?”. The plans for the Norwegian-led Provincial Reconstruction Team (PRT) in Maimanah in Faryab province in Afghanistan is used as a basis ...
    • Coherent range and Doppler-walk compensation in PBR applications 

      Christiansen, Jonas Myhre; Olsen, Karl Erik; Weiss, Georg (2014)
      The focus of PBR research has shifted from FM to also include DVB-T and DAB over the last years, and are facing the challenges of higher bandwidth, i.e. improved range resolution. While the FM based PBR systems primarily ...
    • Detection performance for Incoherent Range Walk Compensation 

      Finden, Erlend; Christiansen, Jonas Myhre; Lie-Svendsen, Øystein; Olsen, Karl Erik (2014-11-24)
      FFI supports the Royal Norwegian Air Force in their acquisition of new air surveillance sensors. Improved detection performance on low observable targets may be obtained by increasing the radar dwell time on target. For ...
    • 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, ...
    • DVB-T based Passive Bistatic Radar 

      Christiansen, Jonas Myhre (2010)
      The interest for bi- and multistatic radar systems has gone in cycles of approximately 15 years. Currently we are at the peak of such a cycle, which mainly is driven by the interest for Passive Bistatic Radar systems. ...
    • Fully adaptive radar for track update-interval control 

      Christiansen, Jonas Myhre; Olsen, Karl Erik; Smith, Graeme E. (2018)
      A fully adaptive radar framework has been proposed in recent publications, and this paper will implement the framework in an adaptive update rate application for a tracking radar. A cost function is developed to balance ...
    • Multiband Passive Bistatic Radar Coherent Range and Doppler-Walk Compensation 

      Olsen, Karl Erik; Christiansen, Jonas Myhre (2015)
      The work simulates the performance of a coherent Passive Bistatic Radar multiband processing algorithm. The aim of the work is to present improved range resolution by coherently combine non-adjacent DVB-T channels, while ...
    • Parameter selection in a fully adaptive tracking radar 

      Christiansen, Jonas Myhre; Smith, Graeme E. (2020-04-27)
      A fully adaptive radar framework has been proposed in recent publications, and this paper will implement the framework for a tracking radar. A set of cost functions are developed to balance the performance cost of the track ...
    • Range and Doppler walk in DVB-T based Passive Bistatic Radar 

      Christiansen, Jonas Myhre; Olsen, Karl Erik (2010)
      This paper analyzes the effects of range and Doppler walk for a Digital Video Broadcast - Terrestrial based Passive Bistatic Radar of both simulated and experimental data. Range and Doppler walk cause energy dispersal ...
    • USRP based cognitive radar testbed 

      Christiansen, Jonas Myhre; Smith, Graeme E.; Olsen, Karl Erik (2017)
      Cognitive radar is a relatively new field of research and the existence of low cost experimental testbeds is limited. This work will show the development of a low cost experimental testbed for experimental validation of ...
