“…Depending on the strength, a two-dimensional image of the region can be obtained. However, detection accuracy, low penetration depth, multiple targets, slope of area and height of the detection cap may cause some problems to be encountered [74] [75]. Metal covered land mines have lower absorbtion-scattering ratio than the plastic mines and soil, their detection by this method is much more difficult [2].…”

“…Metal covered land mines have lower absorbtion-scattering ratio than the plastic mines and soil, their detection by this method is much more difficult [2]. Because of the long determination time (about 22 min), the recent studies have been concentrated on obtaining a good quality of images in a shorter time [75]. Speeding up the process may increase the system weight and volume, but decrease X-ray density.…”

“…In our study, X-ray backscattering method is investigated for buried land mine detection and again the following variables are selected for performance criteria parameters for each work that is examined: soil type, material tested, test height, working rate and frequency, findings under these conditions [74] [75] [76]- [83]. Figure 9 gives the principle of the X-ray method for mine detection.…”

Today, remote sensing is used for different methods and different purposes. In all of the detection methods, some considerations such as low energy consumption, low cost, insensitivity to environmental changes, high accuracy, high reliability and robustness become important. Taking into account these facts, remote sensing methods are used in applications such as geological and archeological research, engineering areas, health services, preserving and controlling natural life, determination of underground sources, controlling air, sea and road traffic, military applications, etc. The method to be used is based on the object type to be detected, material to be made, and location to be found. The remote sensing methods from the past up to today can be listed as acoustic and seismic, ground penetration radar (GPR) detection, electromagnetic induction, infrared (IR) imaging, neutron quadrupole resonance (NQR), thermal neutron activation (TNA), neutron back scattering, X-ray back scattering, and magnetic anomaly detection. In these methods, detected raw images have to be processed, filtered and enhanced. In order to achieve these operations, some algorithms are needed to be developed. In this study, the methods used in detecting land mines remotely and their performance analysis have been given. In this way, the last situation on the advantages and disadvantages of methods used, application areas and detection accuracies are determined. Furthermore, the algorithms such as transmission line matrix (TLM), finite difference time-domain (FDTD), the method of moment (MoM), split step parabolic equation (SSPE) and image processing and intelligent algorithms are presented in detail.

“…The LMR imaging modality employs an array of two types of large sensitive-area detectors. Manipulation of the set of images acquired by this detector array results in systematic removal of mine-image cloaking due to soil surface features and slope [8]. 9) Magnetostatic dipole field or field gradient: It is a method used in practice based on the field gradient.…”

Abstract-There is a variety of methods used for remote sensing of objects such as acoustic, ground penetration radar detection, electromagnetic induction spectroscopy, infrared imaging, thermal neutron activation, core four-pole resonance, neutron backscattering, X-ray backscattering, and magnetic anomaly. The method that has to be used can be determined by the type of material, geographical location (underground or water), etc. Recent studies have been concentrated on the improvement of the criteria such as sensing distances, accuracy, and power consumption. In this paper, anomalies created by materials with magnetic characteristics at the perpendicular component of the Earth magnetic field have been detected by using a KMZ51 anisotropic magnetoresistive sensor with high sensitivity and low power consumption, and also, the effects of physical properties of materials on magnetic anomaly have been investigated. By analyzing the graphics obtained by 2-D motion of the sensor over the material, the most appropriate mathematical curves and formulas have been determined. Based on the physical properties of the magnetic material, the variations of the variables constituting the formulas of the curves have been analyzed. The contribution of this paper is the use of the results of these analyses for the purpose of identification of an unknown magnetic material. This is a new approach for the detection and determination of materials with magnetic characteristics by sensing the variation at the perpendicular component of the Earth magnetic field. The identification process has been explained in detail in this paper.Index Terms-Anisotropic magnetoresistive sensor (AMR), magnetic anomaly, magnetic materials, power consumption, remote sensing.
