For ultra-wideband synthetic aperture radar (UWB SAR), there often exist a lot of clutters in the image, and the weak targets are easy to be masked by them. However, using the prior scattering knowledge of targets, enhanced imaging can be realized and beneficial improvements in image quality and detection performance can be expected. In this paper, an enhanced imaging method for body of revolut...

Syntactic landmine detection has been proposed to detect and classify non-metallic landmines using ground penetrating radar (GPR). In this approach, the GPR return is processed to extract characteristic binary strings for landmine and clutter discrimination. In our previous work, we discussed the preprocessing methodology by which the amplitude information of the GPR A-scan signal can be effect...

This paper presents a new approach to the detection of anti-personnel landmines which is based on the physical detection of landmines using a sharpened probe in a fashion similar to that employed by human deminers. Reviews of current techniques , proposed new sensor technologies, and current uses of robotic devices within landmine detection are presented. This is followed by a description of ou...

As of 1999, the only artificial systems employed by the U.S. military for the detection of buried landmines were metal detectors.1 Although these detectors can sense as little as 0.5 grams of metal, and thus maintain a high detection probability, they cannot distinguish between a firing pin or a piece of scrap metal. Furthermore, modern landmines can be constructed without metallic parts and wo...

In real field demining, soldiers can only judge the landmine location and type by the sound generated from a landmine detector. Therefore, a virtual landmine detection training system can replicate the sound in a realistic manner is imperative. In this paper, several sound datasets for various targets have been collected. Each dataset contains about 500 instances, each representing a different ...

Inexpensive ground-contacting accelerometers have been demonstrated in field experiments as appropriate vibrometers for a seismic landmine detection system. A thirty-two-element line array of these has been used to detect a variety of anti-tank (AT) landmines under realistic field conditions. Images of data measured by scanning this line array to synthesize a larger plane array have shown that ...

This article, presents two robots developed by IntRoSys, S. A.. Poseidon, is a walking robot capable of scanning a large area encompassed by itself with a set of landmine detection sensors. The 3 by 3 m free area encompassed by the structure, plus the wide and accurate mobility of the payload sensors, makes this solution a remarkably useful tool for accurate sensor fusion and consequently for d...
