“…The design of the dipole antenna with operating frequency from 70 MHz until 80 MHz, having cooper material in developing PM GPR system simulation using call setup time (CST) software is as shown in Figure 2 [11]. Referring to the SFCW GPR system, receiving signal of the system needs to be transformed from the time domain into the frequency domain by using the discrete fourier transform (DFT) technique.…”

“…Meanwhile, an iron bar with a diameter of 800 mm Length, 800 mm width and 400 mm height was buried inside a ground object. The detailed information on the PM GPR system simulation model design in CST software and its scanning methods can be referred to the paper [11].…”

“…Referring to the PM GPR system, there are two types of signals involved which are information signal and carrier signal. The difference between the information signal and the carrier signal is that the 4105 information signal has a low-frequency signal using the sinusoidal type while the carrier signal has a highfrequency signal using Gaussian pulse signal [9]- [11]. In contrast, the SFCW GPR system uses only one type of signal that is sinusoidal with variable frequency values.…”

This paper discusses the method of processing the pulse modulation (PM) ground penetrating radar (GPR) system to detect an embedded object underground. The proposed technique is using frequency domain operation which can be classified based on two parameters which are magnitude and phase. The process of detecting the position and depth of iron objects in dry sandy soil is easier to identify using the techniques and parameters that have been introduced. The selection of the Dipole antenna as a sensor device to detect iron objects has been designed in a frequency range of 70 MHz to 80 MHz. Based on the simulation, the proposed technique seems to be able to detect underground iron objects. By using the magnitude value, the underground iron object that can be detected as displayed in GPR radargram is in the depth range from 0 mm until 1000 mm. Meanwhile, by using the phase value, the embedded underground iron object detected is in the range of depth between 900 mm and 1000 mm. Therefore, based on this promising result, the proposed technique and parameters are considered to be used in
