Abstract Submission Deadline 11 October 2022
Manuscript Submission Deadline 11 December 2022

Satellite remote sensing offers great vantage in studying geology, especially in vast, inaccessible landscapes that have limited on-ground datasets. SAR sensors provide a different perspective to geological observations in contrast to optical remote sensing. Day-and-night observations, transparency to haze, fog, cloud, smoke, foliage penetration, side-viewing geometry, observation of electrical properties of the ground targets, and deformation mapping capabilities make SAR satellites an exclusive remote-sensing tool. The launch of Seasat in 1978 launched the era for SAR imaging of the Earth’s surface. At present, we have a constellation of satellites with complex radar imaging capability in multiple frequencies, polarimetry, modes and resolutions. Apart from this, we have archived datasets from previous SAR satellites, which gives us the opportunity to conduct time series analysis in deformation-prone areas. Implications from previous observations can also be used in predictive modelling.

Application of SAR imaging in geoscientific studies is under-explored compared to other fields. The scope for exploring the application of SAR imaging in geoscientific studies is significant, considering the uniqueness of SAR science. There remain many areas where progress can be made. Foliage penetration capability and subsurface viewing ability of SAR in arid and semi-arid regions can be analyzed in studying the Earth’s surface. The potential of SAR imaging in the field of economic geology may also be explored. SAR science may also be applied to oil seepage characterization and modelling in onshore basins, which can be extended to under-explored areas to assess and manage exploration-related risks. Interferometric studies in hazard-prone areas can help in decision-making on disaster-avoidance and mitigation policies.

This Research Topic welcomes original research articles focusing on advancements in geoscientific studies with the aid of space-borne SAR imaging systems. We look forward to articles that explore and analyze the potential of SAR systems and their uniqueness in the field of geology. Apart from Earth observations, we would like to include research on other planetary bodies. Themes that should be included, although not limited to are:

1. Rock characterization in different geological setting;
2. Structure identification and mapping;
3. Soil characterization;
4. Subsurface mapping in arid regions;
5. InSAR and D-InSAR analysis including time series to detect vertical and horizontal land motion;
6. Potential of SAR imaging in ground surface characterization in foliage covered areas;
7. Multi-sensor studies with scope of data fusion;
8. Application of SAR in hydrocarbon exploration (onshore and offshore) and oil spill management;
9. Coal detection and characterization;
10. Hydro-geological studies;
11. Geological observations of celestial bodies.

Keywords: SAR imaging, geological mapping, hydrocarbon exploration, hydrogeological studies, polarimetry, Interferometry, time series analysis
