Nondestructive Inspection of Tree Trunks Using a Dual-Polarized Ground-Penetrating Radar System

In recent years, trees in European countries have been increasingly endangered by emerging infectious diseases (EIDs). the United Kingdom, this has observed to affect whole woodlands and forests, threatening existence of some types trees. Although quarantine measures taken limit spreading such diseases, not yet effectively controlled leading millions affected EIDs. Ground-penetrating radar (GPR) proven effective identifying critical features on diseased for detection EIDs spread. However, irregular shape tree trunks their complex internal structure represent real challenges conventional GPR measurements data processing methodologies. research, a dual-polarised system is used detect decay using novel signal A polarimetric correlation filter based Bragg Scattering 3D Pauli feature vector an arc-shaped Kirchhoff migration are discussed detail. The proposed utilised enhance signal-to-noise ratio (SNR) B-scans due bark trunk high-loss properties trunks. Meanwhile, algorithm performed counteract influence irregularity. framework successfully validated with trunk, where cross-sections were subsequently cut comparison purposes. Outcomes from methodology demonstrate high consistency cross-sections, indicating reliability scheme assessing tree-decay associated
