A method for detecting buried mines in ground penetrating radar (GPR) data using a Hough transform approach is described. GPR is one of three sensors used in the Mine Hunter/Killer (MH/K) system for detecting buried mines. A buried mine modeled as a point scatterer in object space gives rise to a hyperbolic response in GPR measurement space. Our approach uses the Hough transform to recover the ...

This paper describes a new approach to object recognition by using ground-penetrating radar (GPR) imaging systems. The recognition procedure utilizes the spectral content instead of the object shape in traditional methods. To produce the identification feature of an object, the most common spectral component is obtained by singular value decomposition (SVD) of the training sets. The identificat...

This paper provides a comparative study between microwave tomography and synthetic time-reversal imaging techniques as applied to ground penetrating radar (GPR) surveys. The comparison is carried out by processing experimental data collected at a controlled test site, with different types of buried targets at given subsurface depths and representative soil conditions. It is shown that the two t...

In this paper, a comparison of two ground penetrating radar (GPR) systems is presented, the classical bi-static one and the Multiple Input Multiple Output (MIMO) system both using N Vivaldi antennas. For both configurations a Linear Sampling Metthod (LSM) imaging algorithm and Kirchhoff migration technique are used for target detection and localization. The performance of both systems are compa...

In this article a new neural network based method for automatic classification of ground penetrating radar (GPR) traces is proposed. The presented approach is based on a new representation of GPR signals by polynomials approximation. The coefficients of the polynomial (the feature vector) are neural network inputs for automatic classification of a special kind of geologic structure—a sinkhole. ...

ground penetrating radar (gpr) and magnetic methods were used at ghasr-e-shirin town in kermanshah province, southwest of iran for detecting a series of large ancient (ca 1500 years) underground cavities (tagh). the area of study is a historical monument which is named as emarat e khosro. radar and total intensity magnetic field measurements have been done on the eastern part of the complex, wh...

We study the capabilities of low frequency radar systems to sound the subsurface in arid countries. This approach is based on the coupling between two complementary radar techniques: the airborne Synthetic Aperture Radar (SAR) used in L-band (1.2 GHz) for imaging large scale subsurface structures, and the Ground-Penetrating Radar (GPR) used between 500 and 900 MHz for sounding soils at a local ...

The primary objective of the work-in-progress reported here is to compare near-surface imaging results using ultra-shallow (upper 3 m) seismic-reflection techniques and ground-penetrating radar (GPR) at an alluvial site near Great Bend, Kansas. Although various seismic and GPR surveys have been used for near-surface imaging, little i s known about how the two techniques might work in concert fo...

The aim of the paper is to design a digital BPSK modulator for Ground Penetrating Radar applications. . The BPSK (Binary Phase Shift Keying) is one of the three basic binary modulation techniques. It has as a result only two phases of the carrier, at the same frequency, but separated by 180o. In this paper we took modulation as a main stream and analyzed about BPSK modulation technique on Xilin...

Ground penetrating radar (GPR) has emerged as an effective tool for estimating active layer thickness (ALT) and volumetric water content (VWC) within the active layer. In August 2013, we conducted a series of GPR and probing surveys using a 500 MHz antenna and metallic probe around Barrow, Alaska. We collected about 15 km of GPR data and 1.5 km of probing data. Here, we describe the GPR data pr...
