The detection of RDX and TNT mine like targets by nuclear quadrupole resonance

摘要

Nuclear quadrupole resonance (NQR) is being researched in order to confirm the presence of explosives as part of landmine sensor suites for the UK MOD hand held and vehicle mounted detection applied research programmes. A low power NQR system has been developed as a non-contacting, but short range, detection method for explosives typically found in landmines. The results of stand-off detection of buried anti-personnel and anti-tank quantities of RDX and TNT by this system are presented and the differences in the detection of these explosives by NQR are discussed. Signal processing and radio frequency interference rejection methods to improve the performance of NQR explosive detection have been investigated.
