HCM city is the largest city in Vietnam with about 3,000 km of transport roads for 8 min people. There were many sinkholes appeared on the roads during the period of 2009–2010 years of different diameter. The location of those sinkholes is required to be done to forecast safety transportation in future for. We proposed to use GPR technique for location of these sinkholes in the city by Ramac X3M with...
The Kirchhoff migration plays an important role in converting seismic data into images of geological layers according to viewpoint in the applied geophysics. In this paper, the application of the Kirchhoff migration was used in the case of the high frequency electromagnetic method for specifying GPR velocity model. The measurements of raw GPR data collected by Ramac X3M with 500 MHz frequency in HoChiMinh...
