Study of forward and reverse theory and some technique problems in detecting underground pipeline by ground penetrating radar

Abstract：First, it has mainly introduced the ground penetrating radar method and its priciple.Then, it has discussed the reflecting and its explaination method of pipe_shaped objects such as underground pipeline and so on when explored by ground penetrating radar.Some technique methods increasing resolution of ground penetrating radar are sum up. The technique of time gain and space wave filter are introduced. Finally, some representative application examples are given.
