  3. uses radar principles to image, locate and quantitatively identify changes in electromagnetic properties under the ground. Information that can be obtained from GPR includes the depth, orientation, size and shape of buried objects, and the density and water content of soils.

  7. Software The VIY-2 GPR basic software package is compatible with any computers with Win9X and higher operation system. It allows making the GPR adjustment, carrying out the field surveying and executing the acquired data processing. Setup window provides adjustment of survey window, stacking number, step increment and time-varying gain control (TVGC) shape. The tuning results are reflected by received waveform (A-scan) in online V I Y T r a n s i e n t T e c h n o l o g i e s

  8. Experimental Results The VIY-2 GRR was tested for searching of utility lines in Dneprovskiy region, Kiev, Ukraine. Area is sandy soil (approximate electromagnetic wave veloc-ity in the media was fixed as 15 cm/ns). The B-scan presents one of the concrete tubes that was detected on a depth about 4 meters.

  9. Conclusions The VIY-2 ground penetrating radar (GPR) with unique sounding possibilities and use simplicity is presented at this paper. The VIY-2 GPR combines all units (synchronizer, transmitting and receiving mod-ules, powering and antenna system) into single case. The VIY-2 GPR communicates with computer via standard interface RS232 or USB1.0. Technical solu-tions utilized by the VIY-2 GPR reduce deployment time and simplify survey process. The VIY-2 GPR design features and its compo-nents interaction are considered. Field result is also presented. The VIY-2 GPR design concept allows reducing the data acquisition time, optimizing the time-varying gain control function, applying depth-stacking dependence, controlling the survey window position and reducing of interference by providing the pulse repetition frequency randomizing.
