| Abstract: | Ground penetrating radar(GPR) has been used widely in the underground metal mines,and the results of surveying are often influenced by the complicated subsurface environment.It is useful for controlling the environmental interfering signal or removing it from the radar image by distinguishing and analyzing all kinds of interference factors.Several common interference factors often exist during working of GPR under the subsurface environment of metal mine.They discussed combined with some cases of GPR application and author's experiences.The basic characteristic of noisy image is analyzed,and some reasonable processing methods and measures are proposed. |
