Envelope Derivative Operator-based Instantaneous Attributes for Locating Road Cavities

Abstract Ground penetrating radar, as an important means of near-surface detection, is being used more and more extensively in road detection. The instantaneous centroid frequency of ground penetrating radar has good directivity for road cavities, and the research of this group further improves the instantaneous centroid frequency for ground-penetrating radar road detection. In this paper, we will model and simulate ground penetrating radar detection to verify the effectiveness of the improved instantaneous pointing frequency.
