Application of Ground-Penetrating-Radar to Non-destructive Detecting in Concrete Objects and the Key Technique

This paper describes in brief the basic technique of non-destative detecting in Concrete Objects, and intridces GPR (ground-penetrating-radar) methed into the field. Combined with practicalengineering example, it has studied the application effect on non-destructive detecting in concrete objects.For extracting the high-resolution information from GPR data, we perform data processing using fractal technique.
