An Approach to the Simulation of Radar Sounder Radargrams Based on Geological Analogs

IEEE Transactions on Geoscience and Remote Sensing, 2019
Simulation of radar sounder (RS) data is important for understanding the radar response of subsurface features to facilitate the interpretation of the real data. Conventional electromagnetic simulators require the definition of complex geoelectrical models of the investigated targets.

An Integrated Method of PCA and PSM for Localization of Hyperbolic Signatures in Radargram

2020 International Conference on Communication and Signal Processing (ICCSP), 2020
This paper describes an integrated method of Principal Component Analysis(PCA) and Phase Shm Migration(PSM) for GPR data processing. The localization of subsurface objects is carried out by PSM. When the migration method is used the image is defocused due to the ground reflections and is tackled by incorporating PCA based on singular value ...

Automated Data Extraction from Synthetic and Real Radargrams of Complex Structures

Journal of Environmental and Engineering Geophysics, 2018
ABSTRACT This paper presents a comparative study of two algorithms for detecting and analyzing the characteristic shapes of reflection obtained as a result of Ground-Penetrating Radar (GPR) scanning technology. The first algorithm is a sub-array processing method that uses direction-of-arrival algorithms and the matched filter ...

Radargrams as Sequences: A Method for The Semantic Segmentation of Radar Sounder Data

IGARSS 2024 - 2024 IEEE International Geoscience and Remote Sensing Symposium
Radar sounders (RS) are electromagnetic sensors employed for subsurface investigation on Earth and other celestial bod- ies. The data acquired by RS are represented as radargrams and they are traditionally analyzed through visual interpreta- tion or manual feature engineering to detect subsurface layers and relevant features.

Parabola and horizontal line detection in inland water radargrams

2019
Since few years, recent altimetric missions allow us to get valid measurements over inland water. However, most measures remain difficult to analyze and several physical effects were observed, especially the hooking effect with LRM mode in Jason3 mission (e.g. Quartly, Tournadre, … etc).

Rock structures analysis from GPR radargram based on MUSIC method

2017 9th International Workshop on Advanced Ground Penetrating Radar (IWAGPR), 2017
Ground Penetrating Radar (GPR) is a feasible remote sensing tool for surveying subsurface geo-structure. These structure characteristics are recorded in radar signal profiles by means of echo signal detection, amplitude and phase estimation. Besides the energy attenuation and absorption of GPR electromagnetic (EM) pulse during its propagating into ...

Integration of Spectral Datasets and Radargrams in Mawrth Vallis, Mars

This study developed and applied an integrated framework to analyse surface mineralogical variability and radar backscatter response in Mawrth Vallis, Mars. The primary goals were to evaluate the lateral extent and potential subsurface continuity of phyllosilicate-bearing layers, and discussing the benefits, limitations and improvements for this ...

About new - biological inspired - pattern analysis methods for the pattern recognition in radargrams

2015 16th International Radar Symposium (IRS), 2015
Even so ground penetrating radar techniques are well established since many years, the signal analysis of the radar waves lacks still today especially when small ground structures, small objects but also more global soil structures should be detected or interpreted. In this paper we introduce new methods around these weak points.
