TAILIEUCHUNG - GPRTVN – Processing ground penetrating radar data software

This paper introduced GPRTVN processing program which was the research result of the Department of Geophysics for years. This program could process data of many present GPR equipments and quickly provide cross sections of existing underground constructions. It would be very useful for construction and building investigation companies in Vietnam. | TẠP CHÍ PHÁT TRIẺN KHOA HỌC CÔNG NGHỆ CHUYÊN SAN KHOA HỌC Tự nHiÊN tập 2 SÔ 5 2018 97 GPRTVN - Processing ground penetrating radar data software Nguyen Thanh Van Nguyen Van Thuan Dang Hoai Trung Vo Minh Triet Vo Nguyen Nhu Lieu Abstract Designing and mapping underground construction works have been doing for years to meet urgent demands in urbanization process. In this field Ground Penetrating Radar GPR method has shown many advantages in determining underground structures. However our country has almost no processing program that meets demands of processing and interpretation GPR data.

INTRODUCTION GPRTVN the first GPR data processing software in Vietnam was designed by the Department of Geophysics VNUHCM -University of Science. The user interface of GPRTVN was designed for the ease of use with all controls and options available on the window Fig. 1 . The main window was divided into several menus. The first menu was located on the top left of window. This software could read multiple data formats .dt .dt1 .rd3 .dzt and .sgy measured from many present GPR equipments in the world.

GPRTVN software The software could execute all GPR data processing steps. The first step was the time correction noise reduction and gain 5 . The second one was to determine the electromagnetic wave velocity by migration methods or hyperbolic diffraction. The last one is to .
