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 ...
