Research on the Difference Detection Method Based on GPR Data

This paper presents a difference detection method for roadbed disease detection based on GPR, aiming to solve the problems of the low data processing efficiency and detection accuracy. This method is used for difference processing between the radar data acquired at different time. Comparing with many existing data processing method of one - time detection, this novel method can achieve high resolution and high inspection performance while implementing data acquisition at different time. For validation, a detection experiment is conducted in the Fourth ring road in Beijing. With this method, the roadbed disease detection can be converted from the disposable detection technology to periodic monitoring technology, providing effective technical support for urban roads safely.
