Abstract
A nuclear quadrupole resonance (NQR) sensor assembly includes an active sensor coil configured to transmit radiofrequency (RF) signals to an object of interest and receive return RF signals from the object of interest to generate sensor signals substantially representative of the return signals. The at least one reference coil is configured to receive environmental RF signals to generate reference signals at least partially representative of the environmental RF signals. The at least one reference coil is co-located with the active sensor coil. The active sensor coil and the at least one reference coil are in communication with a correction unit configured to remove interference components from the sensor signals using the reference signals.
