Identification of Buried Objects in GPR Using Amplitude Modulated Signals Extracted from Multiresolution Monogenic Signal Analysis

Abstract: It is necessary to detect the target reflections in ground penetrating radar (GPR) images, so that surface metal targets can be identified successfully. In order to accurately locate buried metal objects, a novel method called the Multiresolution Monogenic Signal Analysis (MMSA) system is applied in ground penetrating radar (GPR) images. This process includes four steps. First the image is decomposed by the MMSA to extract the amplitude component of the B-scan image. The amplitude component enhances the target… Show more

“…CO surveys carried out in a silage‐corn field adjacent to the experiment plot using the same 500‐MHz transducers in the same configuration showed both well‐ or ill‐shaped shallow hyperbolas in a radargram without burying reflectors. Integrated or segregated application of modern hyperbola fitting algorithms (Dou et al, ; Mertens et al, ; Qiao et al, ) would increase the efficiency and the accuracy (avoiding the subjective error of hyperbola fitting) of this proposed method. The capability of this approach to be used in the spatial and temporal variation of θ v in managed agricultural fields for efficient water management will be our next research question.…”

“…Some recent research has focused on increasing the efficiency of the hyperbola fitting method by minimizing the human error associated with identifying and fitting hyperbolas. Techniques such as multiresolution monogenic signal analysis are useful to detect hyperbolas accurately (Qiao et al, ). Real‐time detection and fitting of hyperbolas have also been recently investigated (Dou et al, ).…”

“…L vd is the loss due to antenna's vibrations caused by the drone, L t1 is the loss due to the change of the propagation medium (from air to ground), L t2 is the loss due to the propagation from ground to air, L s is the antenna spreading loss, L a is the loss due to signal attenuation and L sc is the target scattering loss. L t1 and L t2 can be calculated considering the power transmission loss coefficient defined as τ =1-|Γ| 2 , where Γ is the reflection coefficient which can be computed knowing the air and soil impedance Z a and Z m , respectively. Assuming a normal impinging wave, Γ is defined as…”

“…However, within the wide range, two kinds of GPR systems can be identified upon the manner in which the data is acquired, either in time domain or in frequency domain. Most of commercial GPR systems in use today employ time domain methods and fixed RF electronics to implement impulse-based radar techniques [1][2][3][4][5] where a time domain pulse is transmitted and the reflected energy is analysed as a function of time. The resulting waveform indicates the amplitude of the backscattered energy from the subsurface structures versus time where range information from objects within the subsurface is based on the time-of-flight principle.…”
