A Multi - frequency GPR Data Fusion Method for Underground Disease Detection

Abstract

This pa per presents a novel multi - frequency GPR data fusion method, aiming to solve the problem of misjudgment and missed judgment due to single frequency GPR data used in the disease detection. Compared with the data before fusion, the image quality and image interpretation accuracy of the fused data is obviously improved. For design validation, field detection experiments are conducted, and the data fusion images are analyzed and evaluated. The method will provide technical support for road safety evaluation.
