Abstract

Measuring the transverse relaxation time of noble gas nuclei with the Free-induction-decay (FID) signal is one of the key technical challenges and prerequisites for the nuclear magnetic resonance gyroscope (NMRG), which is a quantum sensor to form an inertial navigation system. In this paper, a novel method to estimate the parameter of the freeinduction-decay signal based on the adaptive internal model (AIM) controller is proposed and it is verified by the free induction decay data collected from the gyro prototype. In the proposed methods, the AIM con troller can provide estimates of the FID signal, such as the amplitude, the frequency, and the relaxation time. The feasibility of the scheme is proven by theoretical analysis and the reliability of the method is verified by the test results.
