Ground penetrating radar system applied in the underground concealed object detection

Abstract

In the detection of diseases on urban and rural roads and underground pipelines, we require to locate the position of disease or pipeline precisely and obtain relevant information as much as possible. The ground-penetrating radar system in this paper uses differential GPS positioning while recording, to obtain precise location of the disease. It uses high-precision camera systems to collect information on road conditions and reasonably explain the causes of the roadbed disease. Besides, it uses inertial measurement unit to obtain three-axis attitude angles of the equipment timely, which is convenient to locate the survey line inflection point. Through developing a powerful data processing and information extraction software system, it makes use of the collected data more efficiently. The actual experimental results show the geological radar system superiority in the application in highway quality testing.
