2-D AND 3-D DIFFRACTION STAKE MIGRATION METHOD USING GPR: A CASE STUDY IN ÇANAKKALE (TURKEY)

Abstract

In this study, ground-penetrating radar (GPR) method was applied for Clandestine cemetery detection in Çanakkale (Dardanelles), west Turkey. Investigated area was a historical area which was used as tent hospitals during the World War I. The study area was also used to bury soldiers who died during the treatment process in tent hospitals. Because of agricultural activity grave stones were used by local people, thus, most of the graves were lost in the fifield.

45 GPR profifiles were applied with a GPR system (RAMAC) equipped with 250 MHz central frequency shielded antenna. After main processing steps on raw data, migration was applied to improve section resolution and develop the realism of the subsurface images. Although the GPR in results before migration the anomalous zones are visible, after migration the results became much more visible both in the profifiles and 3D illustrations, thus, migrated GPR data were preferred to locate the buried martyrdoms.
