by the use of GPR, various research studies have been conducted to optimize the GPR equipment setup and develop innovative data-processing and analysis techniques. Jack and Jackson used 450-and 900-MHz GPR antennae to provide the image attributes of the ballast and subgrade (1). A fixed electromagnetic (EM) velocity
