Abstract

Ground Penetrating Radar (GPR) is a radar system used to detect objects buried underground. The GPR system consists of an antenna which will be used as a sensor device in detecting microwave signal generated by it, which called monostatic or two antennas used as transmitter and receiver antenna known as bistatic GPR system. In the development of a GPR system, it is wise to simulate the GPR system using simulation software such as CST microwave software in order to reduce errors in determining the parameters of the system such as antenna’s dimension and signal processing system. The design of the simulation system of the GPR system in this study started from designing an antenna, where the microstrip patch antenna has been chosen. The simulation of the design antenna was then upgraded by the designing of the ground material in front of the antenna to create a medium of transmission such as sandy soil. In order to observe the capability of the designed antenna as the GPR antenna system as well as the signal processing system, the buried material in the ground has been added. As the consideration of the GPR system is on the bistatic GPR system, the antenna will be paired between the transmitting and receiving antenna. Based on the commercial GPR system, the simulation of the GPR system will also be interpreted as a 2 dimensional image using MATLAB software.
