    • 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 ...

    • 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 ...

    • 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, ...

    • 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 ...

    • 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 ...
