Application of 3-D migration algorithm to GPR on an irregular ground surface

GPR is a geophysical method which uses electromagnetic pulse radiation to make the image of subsurface and objects in it. The main advantage of the method is that it is nondestructive method. In this paper we proposed to use transformation of coordinates from iGPS system to GPS format for synchronization measurement traces and it coordinates in the RAMAC system. The experimental data was processed by diffraction summation algorithm, because it is universal method. It can takes into account variable velocity case and topographical properties of surface. The experiment result demonstrates the possibility of performing the migration on uneven ground surface.
