Abstract:
Ground Penetrating Rada r ( GPR) is a h igh-reso lution, non-destructiv e geophysica l survey techno logy dev elop ing rap id ly in recen t years. According to the different d ie lectr ic properties o f earth m ater ia ls, the GPR surv eys the underg round structu re by transm itting the high- frequency e lectrom agnetic pulsew ave from the antenna. Since the transm ission process of the radarw ave in the underg round is ve ry com plex, the in terference of a ll k inds o f no ise and clutter is very strong. Through the ana lysis o f the apparent ve loc ity d ifference be tw een effective wave and interference w ave in theGPR and based on the study on the pr inc iple o f 2-dim ensiona l filter ing, a 2-d im ensiona l frequency- w avenumber filter ing is adopted to remove noise in a tim e and frequency dom ain w ay in orde r to deal w ith GPR da ta, and the conclusion show s that the 2-dim ensiona l filte ring can e ffectively rem ove the interference.
