A Deep Learning-Augmented Stand-off Radar Scheme for Rapidly Detecting Tree Defects
Jiwei Qian, Yee Hui Lee, Kaixuan Cheng +4
Tree defect detection is crucial for the structural health screening of trees. Existing nondestructive testing (NDT) techniques for tree defect detection require time-consuming and…
A Depth-Adaptive Filtering Method for Effective GPR Tree Roots Detection in Tropical Area
Wenhao Luo, Yee Hui Lee, Mohamed Lokman Mohd Yusof +1
This study presents a technique for processing Stepfrequency continuous wave (SFCW) ground penetrating radar (GPR) data to detect tree roots. SFCW GPR is portable and enables preci…
Compact Dual-Polarized Vivaldi Antenna for Ground Penetrating Radar (GPR) Application
Hai-Han Sun, Yee Hui Lee, Abdulkadir C. Yucel +2
In this paper, a compact dual-polarized Vivaldi antenna is presented. Four Vivaldi elements are used as radiators, and are positioned obliquely and connected in a horn shape. By ex…
