ABSTRACT AbstractA Nuclear quadrupole resonance detector has been developed. This detector targets to RDX, a high explosive inside an anti-personnel landmine, buried up to 15 cm deep. This detector works well outside an electromagnetically shielded room. It was also mounted an anti-mine vehicle and remotely controlled mine detection is demonstrated in public.

Detection of explosives has the flavor of those mathematical problems that are not invertible. It is easier to hide explosives than to find them. Many approaches have been proposed and executed for the remote detection of explosives, contraband materials, weapons of mass destruction, currency, etc. Most detection technologies suffer from a common problem: the features they look for, such as dis...

A head-mounted camera is a useful tool for studying the usability of mobile devices in the field. In this paper, a computerized visualization method is presented. It includes the target trajectory mapped with the deformable template-based tracking algorithm and landmarks-based relative object registration. A landmine detection training video is used for the case study. The results show that thi...

The best way to find buried ordnance (e.g., landmines) is to detect the explosive packaged inside. This expedient would eliminate detection of the ground clutter, such as shrapnel and stray metal fragments, that produce the great number of false positive signals and which slow down detection rates to unacceptable levels. The detection of the explosive is essentially what trained dogs do as they...

Low-frequency ultra-wideband synthetic aperture radar is a promising technology for landmine detection. According to the scattering characteristics of body-of-revolution (BOR) along with azimuth angles, a discriminator based on Bayesian decision rule is proposed, which uses sequential features, i.e., double-hump distance. First, the algorithm estimates the target scatterings in all azimuth angl...

The development of a low-cost motion capture based landmine detection training system is presented in this paper. Two Nintendo Wii Remotes (Wiimotes) are used to form a stereo vision system to obtain the position and orientation of the simulated physical landmine detector. The position data is used to compute the distance between the detector and a virtual mine, and the distance is used to gene...

-Field experience has shown that soil conditions can have large effects on Ground Penetrating Radar (GPR) detection of landmines. We discuss available models for the prediction of the dielectric constant from soil physical properties including bulk density, soil texture, and water content. The soil dielectric constant determines the attenuation of the radar signal. The contrast between the diel...
