The reflection imagine characteristics of electromagnetic wave on different target
高频电磁波在不同目标体上反射图像特征研究

Aiming at the blank about the application of high frequency electromagnetic wave on Beijing geotechnical exploration,the paper present a study that the GPR technology applies on typical targets in Beijing district.On the base of the different reflection characteristics given high frequency electromagnetic wave on typical targets,we summarize the imagine features.Through establishing the theoretical basis of geologic interpretation,the paper studies and summarizes the radar imagine feature of layer medium,underground conduit,CFG pile,debris tampered pile,cement and earth pile and burrow etc.The results show the well base of next daily detection works.
