Research: Detection and Characterization of Small-Scale Magnetic Fields in Underwater Applications
The detection and characterization of small-scale magnetic fields in underwater applications focuses on the precise identification and analysis of weak magnetic fields generated by anomalies, turbulent flows, and local disturbances. The objective is to employ advanced sensors and digital signal processing techniques to distinguish these fields from background noise and the dominant Earth's magnetic field. Characterizing the sensors ensures they can be optimally tailored and calibrated for the specific requirements of the application.
This characterization is carried out with three-axis coil systems that impose known, homogeneous magnetic fields on the sensor under test. Sensitivity, frequency response, and directional characteristics are obtained over a dense orientation grid, including an adaptive estimate of the impulse response under broadband excitation. The same framework quantifies limitations that dominate weak-signal measurements: departure from linearity and saturation at high field strength, recovery of the noise floor after a strong transient, inter-channel crosstalk, and the intrinsic noise spectrum recorded without applied excitation. The procedure is intended for vector magnetometers such as fluxgate sensors and yields quantities that remain comparable across devices, orientations, and operating conditions. Together, these results specify calibration, equalization, and the usable bandwidth and dynamic range of a given sensor. They provide the basis for real-time processing that resolves small-scale underwater magnetic signatures against sensor imperfections and the much stronger geomagnetic background.
