Using Spatial Diversity to Detect Narcotics and Explosives Using NQR Signals

Jakobsson, Andreas LU and Mossberg, Magnus (2007) In IEEE Transactions on Signal Processing 55(9). p.4721-4726
Abstract
Nuclear quadrupole resonance (NQR) offers an unequivocal method of detecting hidden narcotics and explosives. Unfortunately, the practical use of NQR is restricted by the low signal-to-noise ratio (SNR) and means to improve the SNR are vital to enable a rapid, reliable and convenient system. In this correspondence, we develop two multichannel detectors to counter the typically present radio frequency interference. Numerical simulations indicate that the proposed methods offers a significantly improved robustness to uncertainties in the parameters detailing the examined sample.
