Special Issue Information
Dear Colleagues,
Ground penetrating radar (GPR) is a geophysical method based on electromagnetic (EM) wave propagation into the ground.This high-resolution method utilizes a range of frequencies from 10 MHz up to 2 GHz, and its fields of application are numerous. GPR has been successfully used in hydrological investigations to locate water tables and delineate shallow unconsolidated aquifers, in the surveyal of archaeological sites and architectural heritage, as a critical infrastructure assessment method for use in structures such as roads and bridges, as well as in water supply or other utility networks. Other applications include sedimentology, tectonic faults, agriculture, and civil and geotechnical engineering. Recently, the method has undergone enormous advancements with regard to studying near-surface structures of the far side of the Moon: lunar penetrating radar (LPR). All these applications require dedicated processing, imaging, and intrpretation techniques.
Even though after processing, radargrams depict subsurface dielectric heterogeneities, interpretation is often challenging and physical parameters such as EM velocity, dielectric permittivity, and the attenuation of the EM signal are required for efficient interpretation. In the last few years, in the GPR community, a lot of work has been focused on the estimation of EM velocity into the ground or into structures. The scope of this issue aims to highlight the estimation of this specific attribute, which in its turn has been proven as a useful parameter for both the intrpretation of the suburface and further estimation of other desired parameters (such as dielectric permittivity) or for further processing of the radargrams (such as migration).
Applications in areas including, but not limited to, 3D archaeology and cultural heritage, geology, hydrology, pedophysics, subsurface voids, and planetary studies are encouraged. Accordingly, we invite the submission of papers dealing with progress in the following topics:
- GPR modeling;
- GPR full waveform inversion;
- Velocity estimation via diffraction analysis;
- Multi-offset GPR data and velocity assessment;
- GPR tomography;
- The use of velocity estimation for time lapse GPR studies;
- Migration;
- Borehole GPR studies

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Geosciences is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
