    • Assessing Radar Attenuation in RIMFAX Soundings at the Jezero Western Fan Front, Mars 

      Eide, Sigurd; Casademont, Titus; Shoemaker, Emileigh S.; Brovoll, Sverre; Berger, Tor; Dypvik, Henning; Hamran, Svein-Erik (2024-07-02)
      Estimates of radar attenuation in the shallow Martian subsurface are retrieved from RIMFAX soundings along the Perseverance rover traverse. Specifically, analyzed data is from the Hawksbill Gap area during the rover's first ...

    • In-Body to On-Body Ultrawideband Propagation Model Derived from Measurements in Living Animals 

      Floor, Pål Anders; Chavez-Santiago, Raul; Brovoll, Sverre; Aardal, Øyvind; Bergsland, Jacob; Grymyr, Ole-Johannes; Halvorsen, Per Steinar; Palomar, Rafael; Plettemeier, Dirk; Hamran, Svein-Erik; Ramstad, Tor Audun; Balasingham, Ilangko (2015)
      Ultra wideband (UWB) radio technology for wireless implants has gained significant attention. UWB enables the fabrication of faster and smaller transceivers with ultra low power consumption, which may be integrated into ...

    • Physical Working Principles of Medical Radar 

      Aardal, Øyvind; Paichard, Yoann; Brovoll, Sverre; Berger, Tor; Lande, Tor Sverre; Hamran, Svein-Erik (2013)
      There has been research interest in using radar for contactless measurements of the human heartbeat for several years. While many systems have been demonstrated, not much attention have been given to the actual physical ...

    • Radar imager for Mars’ subsurface experiment—RIMFAX 

      Hamran, Svein-Erik; Paige, David A.; Amundsen, Hans E. Foss; Berger, Tor; Brovoll, Sverre; Carter, Lynn; Hanssen, Leif; Dypvik, Henning; Eide, Jo; Eide, Sigurd; Ghent, Rebecca; Helleren, Øystein; Kohler, Jack; Mellon, Mike; Nunes, Daniel C.; Plettemeier, Dirk; Rowe, Kathryn; Russell, Patrick; Øyan, Mats Jørgen (2020-11-03)
      The Radar Imager for Mars’ Subsurface Experiment (RIMFAX) is a Ground Penetrating Radar on the Mars 2020 mission’s Perseverance rover, which is planned to land near a deltaic landform in Jezero crater. RIMFAX will add a ...

    • Radar sensitivity to human heartbeats and respiration 

      Aardal, Øyvind; Brovoll, Sverre; Paichard, Yoann; Berger, Tor; Lande, Tor Sverre; Hamran, Svein-Erik (2015)
      Human heartbeats and respiration can be detected from a distance using radar. This can be used for medical applications and human being detection. It is useful to have a system independent measure of how detectable the ...

    • Time-lapse imaging of human heart motion with switched array UWB radar 

      Brovoll, Sverre; Berger, Tor; Paichard, Yoann; Aardal, Øyvind; Lande, Tor Sverre; Hamran, Svein-Erik (2014)
      Radar systems for detection of human heartbeats have mostly been single-channel systems with limited spatial resolution. In this paper, a radar system for ultra-wideband (UWB) imaging of the human heart is presented. To ...
