Marusenkov A. . Improvement of the methods for estimation of the metrological characteristics of magnetometric information-measuring systems

. The object is metrological characteristics of magnetometric information-measuring systems; the target is improvement of the methods for estimation of the metrological characteristics of magnetometric information-measuring system without interruption of its normal operation; the methods are mathematical apparatus of differential and integral calculus, statistical methods of data processing and error theory; the new approach lies in: developing of the new method for calibration of weak magnetic meters, which uses geomagnetic variations as a calibration signal, modification of the mathematical model of synchronous measurements by reference and tested magnetometers taking into account spectral characteristics both geomagnetic variations and own noise of fluxgate sensors, synthesis of the improved shape of magnetic field distribution inside compensation coil of fluxgate sensor; the main issue is improvement of the uninterruptible methods for estimation of the metrological characteristics of the information-measuring system for weak magnetic fields investigation, the main results of the work were implemented in scientific and industrial companies; the field is information-measurement systems.
