探地雷达技术近年来在道路检测上应用广泛。国外特别是美国在路用探地雷达方面的研究较早,并取得了一系列的研究成果。美国近年来研发了一种利用探地雷达测定路面厚度的计算机程序———TERRA(Thickness Evaluation of Roads by Radar)。应用该程序可以对路面自动分层,估算各层层厚,还可按照不同的层厚把道路分成不同路段加以描述。
Ground penetrating radar technology has been widely used in road testing in recent years. Foreign countries, especially the United States in the ground penetrating radar earlier, and made a series of research results. In recent years, the United States has developed a computer program that uses ground-penetrating radar to measure the thickness of pavement - the TERRA (Thickness Evaluation of Roads by Radar). Application of the program can be automatically stratified pavement, the estimated layer thickness, but also in accordance with the different thickness of the road into different sections to describe.
