Nonlinear Acoustic Landmine Detection

AIP Conference Proceedings, 2008
Numerous field tests have demonstrated that buried landmines manifest themselves at the surface through linear and nonlinear responses to acoustic/seismic excitation at the frequencies below 1000 Hz. The linear signatures are due to lower impedance of soil above “softer” mine, especially in the vicinity of mine's resonance. These phenomena are utilized

Radiometry for landmine detection

Proceedings of the 1998 South African Symposium on Communications and Signal Processing-COMSIG '98 (Cat. No. 98EX214), 2002
The development of new sensors for landmine detection is an active area of research. Microwave radiometry is a field of remote sensing concerned with the measurement of thermally emitted radiation in the microwave band. This paper describes the design, testing and performance of an experimental microwave radiometric measurement system for use in ...

Canadian teleoperated landmine detection systems. Part I: The improved landmine detection project

International Journal of Systems Science, 2005
The system developed under the Improved Landmine Detector Project is a teleoperated, multi-sensor, vehicle-mounted mine detector for low metal content and non-metallic mines to meet the Canadian requirements for rear area mine clearance in combat situations and peace-keeping on roads and tracks.

LIBS for landmine detection and discrimination

Analytical and Bioanalytical Chemistry, 2006
The concept of utilizing laser-induced breakdown spectroscopy (LIBS) technology for landmine detection and discrimination has been evaluated using both laboratory LIBS and a prototype man-portable LIBS systems. LIBS spectra were collected for a suite of landmine casings, non-mine plastic materials, and "clutter-type" objects likely to be present in the

Nonlinear acoustic techniques for landmine detection

The Journal of the Acoustical Society of America, 2004
Measurements of the top surface vibration of a buried (inert) VS 2.2 anti-tank plastic landmine reveal significant resonances in the frequency range between 80 and 650 Hz. Resonances from measurements of the normal component of the acoustically induced soil surface particle velocity (due to sufficient acoustic-to-seismic coupling) have been used in ...

Landmine detection using feedback NQR

SPIE Proceedings, 1999
Nuclear quadrupole resonance (NQR) is well suited for detecting land mines with non-metallic cases. It provides both spatial localization and chemical identification of explosives. A search coil produces a train of radio frequency (RF) magnetic pulses that perturb the orientation of nitrogen nuclei contained within the explosive material.

Sensor management for landmine detection

SPIE Proceedings, 2005
A method known as active sensing is applied to the problem of landmine detection. The platform utilizes two scanning sensor arrays composed of ground penetrating radar (GPR) and electromagnetic induction (EMI) metal detectors. Six simulated confirmation sensors are then dynamically deployed according to their ability to enhance information gain ...
