主 题：urban underground space safety 3D ground-penetrating radar detection of the abnormal bicubic fitting algorithm high-precision imaging
摘 要：3D ground-penetrating radar has been widely used in urban road underground disease detection due to its nondestructive,efficient,and intuitive ***,the 3D imaging of the underground target body presents the edge plate phenomenon due to the space between the 3D radar array ***,direct 3D imaging using detection results cannot reflect underground spatial distribution *** to the wide-beam polarization of the ground-penetrating radar antenna,the emission of electromagnetic waves with a specific width decreases the strong middle energy on both sides ***,a bicubic high-precision 3D target body slice-imaging fitting algorithm with changing trend characteristics is constructed by combining the subsurface target characteristics with the changing spatial morphology *** the wide-angle polarization antenna’s characteristics in the algorithm to build the trend factor between the measurement lines,the target body change trend and the edge detail portrayal achieve a 3D ground-penetrating radar-detection target high-precision *** with other traditional fitting techniques,the fitting error is *** paper conducts experiments and analyses on GpaMax 3D forward modeling and 3D ground-penetrating measured radar *** experiments show that the improved bicubic fitting algorithm can eff ectively improve the accuracy of underground target slice imaging and the 3D ground-penetrating radar’s anomaly interpretation.
