Man portable mine detector using nuclear quadrupole resonance - first year progress and test results

Nuclear quadrupole resonance for explosive detection

“…On the other side, according to [47], RFI was the main factor affecting landmine detection performance and making the analogy that RFI and MAPER are to NQR as clutter is to ground penetrating radar (GPR) [10], solutions to clutter in GPR literature can be extrapolated to NQR. In most GPR literature landmine detection is seen as a two categories classification task: mine class and no mine class (i.e.…”

Design of a radio-frequency transceiver coil for landmine detection in Colombia by nuclear quadrupole resonance

“…Design of the RF coil strongly affects the range and sensitivity of the NQR system as the coil is responsible for sending RF pulses at the specific target frequency for efficient excitation of the substance, and for picking up the weak NQR signal by Faraday's law of induction, usually in a noisy environment. However, in most publications about landmine detection by NQR [1,2,3,4,5], little attention has been paid to NQR coil design. An exception is the work of Farantatos et al [6], who made an electromagnetic design of a spiral coil in COMSOL Multiphysics for landmine detection; however, they did not considered noise as an important parameter in the design.…”

Advances in the engineering of quadrupole resonance landmine detection systems

“…The first published work in the area resulted from work performed by Professor Robert Marino and Bloch Engineering in the 1970's and early 1980's 3, 7, 10, 11 . Quantum Magnetics has been investigating QR for landmine detection [12][13][14][15][16][17] since 1997 and continues work in this area in collaboration with the Naval Research Laboratory (NRL) 4,18,19 . For a more complete review of the technology and history of QR for landmine detection see the 2001 review article written by NRL and Quantum Magnetics 4 .…”
