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 discontinuties in electrical conductivity, are not unique properties of the target but are contained, to some degree, in the more benign surroundings. Such a degeneracy leads to "clutter" in the response. For example, resolving the false alarms generated by this clutter can determine the rate of advance of a conventional electromagnetic metal detector employed as a landmine detector. One approach that provides a "unique" signature is nuclear quadrupole resonance (NQR) (the technique is also called QR, to avoid confusion with strictly nuclear techniques). This paper outlines the important physical principles behind the use of NQR for remote detection, indicates areas of applicability, and presents recent results of field trials of a prototype landmine detection system.

“…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 .…”

Advances in the engineering of Quadrupole Resonance (QR) sensors for landmine detection have resulted in improved performance, as well as massive reductions in power, size and weight. The next generation of vehicle-mounted QR confirmation sensors is over an order of magnitude smaller and more power efficient than the system fielded in 2002 and 2003. Early prototypes have also demonstrated a significant improvement in TNT sensitivity, and similar improvements are anticipated in RDX sensitivity during Q1 2005. Blind test results from 2003 confirm the radio frequency interference and piezo-electric ringing immunity of the Quantum Magnetics QR Confirmation Sensor (QRCS).

Northeastern University is heading one of three teams involved in five year, $5,000,000Multidisciplinary University Research Initiative (MTJRI) programs in demining, supported by the Army Research Office. The Northeastern effort involves a team of six other universities and small businesses and integrates electromagnetic, acoustic, and optical sensing modalities. We are designing sensors to measure many of the physical characteristics of the ground with and without mines, and developing carefully-tailored signal processing algorithms that specifically take the sensor and the physics into account.
