Ground Penetrating Radar uses radar pulses to image the subsurface of underground. This nondestructive method uses electromagnetic radiation in the microwave band of the radio spectrum, detects the reflected signals from subsurface structures. It uses high frequency radio signal that is transmitted into the ground and reflected. Signals are returned to the receiver and stored on digital media. Various signal processing methods are used to measure the time taken for a pulse to travel to and from the target which indicates its depth and location. In this project we aimed to measure the height and detecting various electrical properties using signal processing methods: Averaging calibration technique and Layer stripping approach. The former method is used for calibrating the GPR system and the later method is used to determine spectral parameters of different layers and to reconstruct the physical and geometrical properties of target media. GPR real data is considered for this experiment. The experimental results are presented here for showing the accuracy of the measurement techniques used.
