https://doi.org/10.32446/0368-1025it.2020-9-60-66
Abstract
Results of synchronous electric and magnetic fields measurements made by different types of sensors in the frequency range of 0.002–7000 Hz are covered. Different approaches to obtaining the evaluation of sensor noise are considered. The technique of quantitative estimation of level of natural noise of each sensor and characteristics of a natural field on the basis of two- and three-channel scheme of synchronous measurement is given. Comparison of experimental noise estimations with computational ones is given. It is shown that the magnetometer based on magnetomodulation transducer has an unacceptably high level of its self noise for using it in applications related to the measurement of natural geomagnetic field.
