Effect of the nonuniformity of the radio-frequency field of the sensor of an NQR detector of explosives on the signal intensity and the possibility of its compensation

Russian Physics Journal Aims and scope

Abstract

The intensities of 14 N NQR signals have been calculated in relation to the amplitude of the initiating radiofrequency (RF) field of the radiopulse, the pulse duration, and the detuning. It is discussed whether it is possible to compensate the decrease in intensity of signals from some regions of an explosive which is in a nonuniform RF field by varying the detuning and the duration of the initiating pulse.
