Abstract

A new Ground Penetrating Radar (GPR) system, which is a combination of Optical Fiber Sensor (OFS), GPR and optical communication link, is developed to determine the depth and the position of the buried circular cylinder. Optical Fiber Sensor offers the advantage of Electromagnetic Interference (EMI) immunity and low amplification noise. In this study the electric field distribution at the OFS caused by the Continuous Radio Wave (CRW), which is transmitted from the GPR antenna, is obtained mathematically and its corresponding OFS output voltage measurement is simulated. Various plots are obtained by changing the depth of the cylinder and the operation frequency of the system. Plots exhibit a relation between x axis displacement and measured OFS voltages, and the resultant interference fringe patterns are analyzed. The depth and the position of the cylinder can be determined using interference fringe patterns. © 2012 IEEE.
