The Study of Proton Magnetometer Precession Signal Extraction Technology

摘要

In order to improve the accuracy and stability of the frequency measurement of proton magnetometer precession signal, most of existed methods had been taken. However, many of them may be much better if they had considered the signal detection in a dynamic measurement and strong noisy environment. So a new method based on SCW-controller (Superposition-correlation and Wavlet Controller) is proposed in this study. It focuses on discussing the mathematical model of proton magnetometer precession signal, describing the design of SCW-controller, then the proton magnetometer precession signal is processed both in this new ways, and the performance parameters such as SNR and RMSE are calculated. Finally, experiments and simulations were conducted to show the effectiveness and feasibility of the new development.
