Preservation of Historically and Scientifically Important Geospatial Data From Venus

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract A large volume of scientifically and historically important data from the early exploration of Venus is not widely available to researchers. Our work is focused on ameliorating this problem with the archival of geospatial data including radar, topography, and radiometry.

Ground Penetrating Radar Radargram Filter using Singularity Expansion Method

2020 International Applied Computational Electromagnetics Society Symposium (ACES), 2020
In this paper, the singularity expansion method (SEM) is used to improve the signal-to-clutter ratio of radargrams obtained with a ground penetration radar (GPR). SEM allows to select the poles of the GPR signals corresponding to unwanted signals, clutter, and also reflections of specific buried objects.

Revealing the Internal Structure of Mars‐Analog Glaciers From Drone‐Based Radar Sounding

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Martian debris‐covered glaciers (DCGs) contain large quantities of water ice beneath a protective layer of rock and dust. Properties of the overlying regolith such as density and depth to ice are critical parameters for guiding in situ resource utilization (ISRU) of water and coring missions targeting potential habitats.

Application of impulse radar to continuous profiling of tephra-bearing lake sediments and peats: an initial evaluation [PDF]

, 1985
Subsurface interface radar SIR, or impulse radar, uses electromagnetic pulses for continuous stratigraphic profiling. It has been applied to lake sediments (dy-gyttja) and peat deposits containing a sequence of thin, late Quaternary, ash-grade tephras at

Intrusion‐Induced Forced Folding Model for the Origin of Séítah Formation Domes on the Jezero Crater Floor, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The JPL rover Perseverance's investigations of Jezero crater's floor reveal that the ultramafic Séítah formation and the overlying mafic Máaz formation are deformed into a broad, low‐amplitude structural dome. Mastcam‐Z stereo images processed into digital outcrop models, together with RIMFAX ground‐penetrating radar profiles, were used to ...

An Adaptive Non-Reference Approach for Characterizing and Assessing Image Quality in Multichannel GPR for Automatic Hyperbola Detection

Applied Sciences
The automation of the detection infrastructure in GPR imagery is a key issue, particularly in the context of the non-invasive acquisition of radargrams with a multi-antenna ground-penetrating radar.

Verifying design plans and detecting deficiencies in concrete bridge using GPR [PDF]

, 2006
During the construction of concrete structures such as bridges, many deficiencies may occur due to an incorrect application or changes in the original design plans and construction errors.

Impacts of Temperature‐ and Stress‐Dependent Rheology on Ice‐Shelf‐Front Bending

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.
Abstract Classical treatments of ice‐shelf bending suggest that shelf fronts should bend downwards, due to the distribution of hydrostatic water pressure at the front. However, LiDAR data show several instances of upward‐bending ice‐shelf fronts. While this phenomenon has often been attributed to a buoyant force from a submerged ice bench, recent work ...

Controlled laboratory test for the investigation of LNAPL contamination using a 2.0 GHz ground penetrating radar [PDF]

, 2017
Groundwater is an important source of fresh water and, consequently, its quality should be properly monitored. Different contaminants can be identified with different types of equipment and/or measurement procedures.
