“…We developed a MIMO GPR system "Yakumo" shown in Figure 8, for scanning a large area [13][14][15]. Yakumo was developed for surveying 1-2 m in depth, which is relatively deep compared to the similar multi-static GPR systems.…”

We show the concept of multiple-input multiple-output (MIMO) radar and introduce practical applications, which include ground based synthetic aperture radar (GB-SAR) and ground penetrating radar (GPR). As an example, a 17 GHz MIMO GB-SAR system to be used for landslide monitoring and infrastructure measurement is described. We also show that a MIMO GPR system “Yakumo” can achieve dense three-dimensional (3D) subsurface imaging compared to conventional GPR. We also explain that MIMO GPR can be used for common midpoint (CMP) measurement, which can be used for the estimation of the vertical profile of EM velocity, which is related to soil moisture.

“…The algorithm is considered a computational efficiency algorithm which has an ability to produce high accuracy in signal levels [19]- [21]. As the FFT analysis is a Fourier transform that converts signals from the time domain to the frequency domain [22]- [24], based on this algorithm, the important value of the signal in time will be stored, and exponent components will be calculated repeatedly to complete the history of time [25], [26]. The transformation signal calculated using this algorithm can be classified into two parameters which are magnitude and phase calculation.…”

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

“…GPRs mainly use video pulse probing signals [17,18] and signals with linear frequency modulation [19][20][21][22]. In [23] for georadars installed on unmanned aerial vehicles (UAV), a probing signal with a zero autocorrelation zone (ZACZ) was proposed for georadar working in a quasi-continuous operation mode.…”

Modern ground penetrating radars (GPR), designed to determine the thickness of ice or search for the occurrence of aquifers in arid regions of the Earth, are installed either on helicopters or on the earth's surface. The use of a helicopter is economically expensive, and the installation of GPRs on the earth's surface is of a local nature. Modern GPRs mainly use video pulse probing signals and probing signals with linear frequency modulation. These signals have correlation noise, which makes it difficult to obtain a high-quality radar image. In this work, we propose to use a signal with a zero autocorrelation zone (ZACZ) as a probing signal for GPR installed on an unmanned aerial vehicle. In work, a polyphase probing signal with a ZACZ is synthesized and a comparative analysis of the correlation characteristics of the synthesized signal with the optimal phase-code shift keyed signal is carried out.
