Using these correlations, methods for measurement data fusion and adaptive filtering are determined and optimized. Correlation relationships are established through the analysis of Allan Variance to determine the dominant mechanisms of the instability of the measurement conversion. Measurement data fusion and adaptive filtering methods are implemented on the basis of digital Kalman filters adaptive to specific measurement conditions. Approbation of the developed equipment for magnetic diagnostics was carried out in the world's most powerful experimental reactor for studying the processes of controlled thermonuclear fusion with plasma content in the magnetic field of the Joint European Torus (JET).
