Research on Spectrum Characteristics of Ground Penetrating Radar for Road Underground Water-rich Body

Studying the GPR spectrum response of the road underground water-rich body will help to detect the road underground water-rich body disease and provide a decision-making basis for road safety management and hidden danger management. This paper adopts the method of model simulation and radar measured data to comprehensively analyze different types of water-rich bodies and explore the law of spectrum response of water-rich bodies. The research results show that the radar reflection wave of water-rich bodies has the characteristics of low frequency and strong reflection, decays rapidly, and has reflected wave. The conclusion shows that it is feasible and effective for ground penetrating radar to detect road underground water-rich diseases.
