3DInvNet: A Deep Learning-Based 3D Ground-Penetrating Radar Data Inversion

1 code implementation9 May 2023 Qiqi Dai, Yee Hui Lee, Hai-Han Sun, Genevieve Ow, Mohamed Lokman Mohd Yusof, Abdulkadir C. Yucel

The reconstruction of the 3D permittivity map from ground-penetrating radar (GPR) data is of great importance for mapping subsurface environments and inspecting underground structural integrity.

Diameter Estimation of Cylindrical Metal Bar Using Wideband Dual-Polarized Ground-Penetrating Radar

no code implementations26 Dec 2022 Hai-Han Sun, Weixia Cheng, Zheng Fan

To address the issue, we propose a reflection power-based method by exploring the relationship between the bar diameter and the maximum power of the bar reflected signal obtained by a wideband dual-polarized GPR, which circumvents the resolution limit of the existing pattern-based method.

A Deep Learning-Based GPR Forward Solver for Predicting B-Scans of Subsurface Objects

no code implementations13 Jul 2022 Qiqi Dai, Yee Hui Lee, Hai-Han Sun, Jiwei Qian, Genevieve Ow, Mohamed Lokman Mohd Yusof, Abdulkadir C. Yucel

To alleviate the computational burden, a deep learning-based 2D GPR forward solver is proposed to predict the GPR B-scans of subsurface objects buried in the heterogeneous soil.

Dual-Cross-Polarized GPR Measurement Method for Detection and Orientation Estimation of Shallowly Buried Elongated Object

no code implementations17 May 2022 Hai-Han Sun, Yee Hui Lee, Wenhao Luo, Lai Fern Ow, Mohamed Lokman Mohd Yusof, Abdulkadir C. Yucel

In addition, we present a dual-cross-polarized orientation estimation (DCPOE) algorithm to estimate the object orientation from the two cross-polarized data.

Learning to Remove Clutter in Real-World GPR Images Using Hybrid Data

no code implementations17 May 2022 Hai-Han Sun, Weixia Cheng, Zheng Fan

Existing clutter removal methods either leave residual clutter or deform target responses when facing complex and irregular clutter in the real-world radargram.

DMRF-UNet: A Two-Stage Deep Learning Scheme for GPR Data Inversion under Heterogeneous Soil Conditions

no code implementations16 May 2022 Qiqi Dai, Yee Hui Lee, Hai-Han Sun, Genevieve Ow, Mohamed Lokman Mohd Yusof, Abdulkadir C. Yucel

In the first stage, a U-shape DNN with multi-receptive-field convolutions (MRF-UNet1) is built to remove the clutters due to inhomogeneity of the heterogeneous soil.

Estimating Parameters of the Tree Root in Heterogeneous Soil Environments via Mask-Guided Multi-Polarimetric Integration Neural Network

no code implementations27 Dec 2021 Hai-Han Sun, Yee Hui Lee, Qiqi Dai, Chongyi Li, Genevieve Ow, Mohamed Lokman Mohd Yusof, Abdulkadir C. Yucel

However, the task of estimating root-related parameters is challenging as the root reflection is a complex function of multiple root parameters and root orientations.

The Orientation Estimation of Elongated Underground Objects via Multi-Polarization Aggregation and Selection Neural Network

no code implementations29 Jan 2021 Hai-Han Sun, Yee Hui Lee, Chongyi Li, Genevieve Ow, Mohamed Lokman Mohd Yusof, Abdulkadir C. Yucel

The horizontal orientation angle and vertical inclination angle of an elongated subsurface object are key parameters for object identification and imaging in ground penetrating radar (GPR) applications.
