Abstract
A multi-channel detector for narcotics and explosives using nuclear quadrupole resonance (NQR) is developed. Multiple measurement coils are used to estimate the radio frequency interference that is often present. The temperature dependency of the NQR frequencies is incorporated in the detector, allowing for uncertainties in the temperature estimate of the sample. In addition, the detector considers only the frequency bands of the signal of interest
