Summary: Radio frequency interference (RFI) is a concern for future synthetic aperture radar (SAR) missions due to increased frequency occupation demands. The use of multichannel SAR with digital beamforming (DBF) for RFI mitigation allows for spatial filtering of received signals, removing RFI from different directions. Utilizing auxiliary beams allows for RFI mitigation without drawbacks, as shown in simulated results.

Summary: This paper discusses an experimental approach to the archaeological study of Roman camps in NW Iberia using ground-penetrating radar (GPR) and other survey techniques. The main goal is to explore the capabilities of GPR in extracting datasets from temporary features and improve understanding of these sites before excavation.

Summary: This article presents a novel calibration approach that uses internal signal reflections in the measurement system to derive the system-specific time delay without the necessity of knowing the medium between the antennas. The approach is capable of identifying and correcting for hardware fabrication differences, as well as temporal changes in time-zero during experiments. It reduces the error in time-zero to below 25 ps, enabling high-resolution soil research. The approach requires no additional calibration setups or measurements since all necessary data can be acquired during the original soil measurement.

Summary: A new azimuth relocation method for multichannel SAR is proposed in this letter to address the azimuth location shift of ground moving targets in SAR images due to radial motion. By analyzing the signal and estimating parameters, the proposed method demonstrates higher accuracy and eliminates azimuth location ambiguity issues compared to existing radial velocity-based relocation methods.

Summary: An improved Crack Unet model based on the Unet semantic segmentation model is proposed for 3D ground-penetrating radar crack image processing. The experiment showed that the model displayed better capacity in the radar image crack segmentation task than current mainstream algorithms do, and it has excellent engineering application value.

Summary: In this study, a method for improving the detection of hyperbola in ground-penetrating radar (GPR) images is proposed. The method utilizes phase symmetry to enhance feature resolution and robustness, and constructs a handcrafted feature descriptor based on phase symmetry to extract structural information. Experimental results demonstrate that the proposed method outperforms other methods on different datasets.

Summary: Ground penetrating radar(GPR) is widely used in root detection, but there is little research on automatic reconstruction of root system architecture(RSA) based on GPR. This study successfully reconstructed RSA from the aspects of topological structure and geometric features, and the proposed algorithm enriches the three-dimensional visualization method of RSA.

Summary: This study utilized Ground-Penetrating Radar (GPR) analysis to investigate the internal sedimentary architecture of select coastal tracts in Northern Tuscany, providing insights into dune formation and evolution. The stable or accreting coastal sectors exhibit radar features indicative of beach progradation, while areas affected by erosion hinder coastal progradation and favor destructive events. The GPR profiles effectively delineate recent/ongoing coastal sedimentary budgets by identifying radar features linked to construction/destruction phenomena and dune nucleation/evolution.

Summary: This study investigates the impact of receiver timing jitter on the quality of imaging of ground-penetrating radar systems, showing the residue of coupling noise induced by jitter throughout the processing pipeline. It reveals that simple filtering is not sufficient to remove the residue and proposes linear slope and migrated probability specifications for assessing the severity of coupling signals in a given jitter environment.

Summary: Comparing the observed brightness of various buried objects is a direct way to assess a ground penetrating radar (GPR) system's performance, but distinguishing between the effects of the system itself, its operating environment, and the objects being observed can be challenging. This study developed models of buried object brightness using data from different multistatic radar arrays, allowing for a quantification of the relative brightness of GPR systems and the objects they detect. The study also introduced a method for estimating the probability that individual observations constitute visible objects, aiding in failure analysis, performance characterization, and dataset cleaning.

Summary: One of the main limitations of using ground-penetrating radar (GPR) for landmine detection is the interference from clutter, which raises the detection threshold of the system. Characterizing the internal structure of a target may provide key information for developing algorithms to differentiate between landmines and clutter. Through numerical assessment and experimental validation, it has been found that it is possible to identify and characterize the scattering components in the GPR signature of a landmine.

Summary: Ground Penetrating Radar (GPR) has proven to be a successful technique for detecting landmines and IEDs, with novel architectures improving safety and speed of detection. A hybrid GPR architecture combining advantages of Forward-Looking and Down-Looking GPR has been experimentally validated, aiming to reduce clutter and increase dynamic range in detection. Compact radar modules operating in the lower SHF frequency band were used for realistic target validation.

Summary: To address the computational cost issue in modeling GPR reflection data on glaciers, the authors propose a semi-analytical method based on the assumption of a homogeneous background medium. By representing scattering surfaces with planar elements and considering the antenna radiation pattern, this method can produce realistic 3D GPR data in a fast and memory efficient way. The algorithm is validated with an analytical solution for a layered model and applied to simulate radar data for the Otemma glacier in Switzerland.
