    • 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 ...

    • Radar Attenuation in the Shallow Martian Subsurface: RIMFAX Time-Frequency Analysis and Constant-Q Characterization Over Jezero Crater Floor 

      Eide, Sigurd; Casademont, Titus; Berger, Tor; Dypvik, Henning; Hamran, Svein-Erik; Shoemaker, Emileigh S. (2023-04-16)
      Attenuation of radar waves in the subsurface can be quantified with a constant-Q approximation through time-frequency analysis. We implement the centroid frequency-shift method and study Radar Imager for Mars' Subsurface ...

    • 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 ...

    • RIMFAX Ground Penetrating Radar Reveals Dielectric Permittivity and Rock Density of Shallow Martian Subsurface 

      Casademont, Titus; Eide, Sigurd; Shoemaker, E.S.; Liu, Y.; Nunes, D.C.; Russell, P.; Dypvik, Henning; Amundsen, Hans E. Foss; Berger, Tor; Hamran, Svein-Erik (2023-06-02)
      The Mars 2020 Perseverance Rover is equipped with the RIMFAX ground penetrating radar instrument which has been continuously surveying the shallow subsurface during the rover's journey. Within the first 379 mission ...
