    Gives no technical details, but tells roughly what applications are handled by each method. Methods include ground resistance, magnetometer measurements, and ground-penetrating radar.
 
 

Detection Methods

 Metal Detection
    The metal detector is the most popular sensor to detect mines. Unfortunately many mines are mostly plastic.

Prodding the Ground
    Prodding by hand is presently the only way that guarantees an exhaustive detection of any landmine.
Ground Conductivity

Mechanical
    Clearing mine fields by modified tanks, trucks and tractors.

Acoustics and Acoustic Imaging

Photoacoustic Spectroscopy
    Pulsing a laser in air causes molecules in the air to heat and cool. This cycling causes an acoustic wave the energy and spectrum of which can identify the molecules. Jaycor has a project in this area. [Brief Mention]

Thermal Imaging, IR.
    Buried mines have a different density than the surrounding ground - thus retaining or dissipating heat at a different rate. These temperature differentials can be seen at seen at dawn and dusk.

Plant indicators
    A not yet explored idea to find buried mines is to breed plants sensitive to the presence of TNT in the soil. [Brief Summary]

Odor sensor
    Dogs are used to find mines. They are good for finding isolated mines, or whether a field is mined.
Cal Tech is working on an artificial nose. [Brief Mention]

Antibodies and Genetically Engineered Biosensors
    Antibodies are very selective to other molecules. Could they be made sensitive to TNT? [Brief Summary] Some people even talk about genetically engineered cockroaches.
In Sweden, Bofors Applied Technology used a quartz crystal covered with antibodies. When TNT binds to the antibodies, the crystal frequency changes [Brief Mention]

Forced reaction of TNT by Laser
 Light energy triggers the explosive reaction of the TNT molecule. The heat increase can then by detected. The IBM research lab in Switzerland has found a new type of temperature sensor based on the deformation of nano-technology cantilever beams. [Brief Summary] Barringer Technologies is usin g this for mine detection. [Brief Mention]

Ion Mobility Spectrometry (IMS)
    IMS separates ionized molecular compounds on the basis of their transition times when subjected to an electric field in a tube. This time is then compared to stored transition times of known compounds. Therefore it is possible to distinguish TNT from other molecules. This technique is fast. [Brief Summary]

Ion-Trap Mass Spectrometry
    Molecular ions corresponding to explosives are excited to dissociate into fragments. Negative ions are attracted by a potential and fall into traps according to mass and charge. [Brief Mention]

Reversal Electron Attachment Detector
    When high electronegative groups like NO2 are hit by low energy electrons the electrons attach efficiently. A detector using this is being developed at NASA's JPL. [Brief Mention]

Impulse Radar or Microwave
    The measure of the resonance frequencies of the ground to a radar impulse depends on buried objects. At frequencies whose wavelengths are comparable to the overall size of the object, the smaller details of the structure are irrelevant, making it possible to easily identify the general shape and the material properties of a body.  [Brief Summary]
Jaycore describes its radar system that excites the self-resonant frequencies of targets.

Surface-Penetrating Radar

Thermal Neutron Excitation
    Slow (thermal) neutrons activate nitrogen and chlorine and cause them to emit gamma rays of known spectra.
Science Applications International and DREO have developed prototypes. [Brief Mention]

Nuclear Quadrapole Resonance
    Probing Nitrogen-14 with certain radio frequencies will give characteristic signals in the same way an NMR scan in a hospital does. Quantum Magnetics is developing detectors. [Brief Mention]
J. Humanitarian Demining devotes 2  pages to NQRs in its survey and gives several journal references.

X-ray Tomography
    In X-ray tomography, the emitted radiation, either in the form of neutrons or gamma rays, is designed to react with different elemental components of the object of interest to produce a reaction particular to the specific detector application.  [Brief Summary], [Mention]

National Center for Physical Acoustics, University of Mississippi
Dr. James Sabatier uses acoustics to find buried objects including landmines.
In a recent initial round of tests at Fort A.P. Hill near Fredericksburg, Va., a technique devised by Dr. James Sabatier detected 100 percent of the antipersonnel and antitank mines without a single false alarm. The system uses sound waves and laser beams to scan the ground's surface and identify vibrational patterns produced by buried mines.
