This paper presents a novel method for detection of multiple landmines using a ground penetrating radar (GPR). Conventional algorithms mainly focus on detection of a single landmine, which cannot linearly extend to the multiple landmine case. The proposed algorithm is composed of four steps; estimation of the number of multiple objects buried in the ground, isolation of each object, feature ext...

Results for different parameter T Cell Averaging based threshold algorithm Abstract — Magnetic field mapping is one of the techniques that may be used during the continuation period of an on-site inspection. Iron buried objects induce anomalies in the earth’s magnetic field that appear on the surface below items and that can be measured by a magnetometer. In this work, two approaches already us...

A recently developed apparatus permits the detection of buried objects, such as landmines, by remotely sensing the variations of ground vibration that occur over the buried object with a laser Doppler vibrometer ~LDV!, when the ground is insonified by means of acoustic-to-seismic coupling. As it is currently implemented, the LDV scans individual points on the ground. The technique shows much pr...

Electrical impedance tomography (EIT) is a technology developed to image the electrical conductivity distribution of a conductive medium. The technology is of interest because of its low cost and also because the measurement of the electrical conductivity brings direct information about the composition of the conductive medium. Because the ground is conductive to a certain extent, the technolog...

Relative to the first two long-term goals our specific objective for FY07 was to document both the results from the Sediment Acoustics Experiment in 2004 (SAX04) and the associated analysis and modeling techniques that were developed. Those results include (1) measurement of backscattering levels from buried objects at subcritical grazing angles using synthetic aperture sonar (SAS) measurements...

Ground penetrating radar (GPR) is one of the common sensor system used for underground inspection which emits electromagnetic waves that can pass through objects. The reflecting waves are recorded and digitized, and then, the images are formed. According to the properties of scanning object, GPR creates higher or lower intensity values on the object regions. Thus, these changes in signal repres...

Since WWII acoustic echo-location method utilized in sonars has been one of the primary approaches for detecting underwater mines. However, earlier attempts to replicate sonar approach and its modifications for detection of landmines were not successful. For example, Caulfield, 1989, House & Pape, 1994, Don & Rogers, 1994 suggested the use of acoustic impulse reflection from soil. A buried obje...
