Abstract:
The problem of determining the parameters of an object's magnetic field from the results of remote magnetogradient measurements is considered. The task is set to determine the magnetic parameters of an object based on a description of its influence on the measuring system as a magnetic dipole vector. A key feature of the proposed approach is the use of differences between spaced sensors directly, rather than as an estimate of the corresponding spatial derivatives. The problem of determining the magnetic parameters of an object using a tensor meter, built on the differences between field components, and a vector meter, built on the differences in field modules, has been solved. The proposed algorithms are implemented in the software of a computer simulation model, which makes it possible to simulate the process of determining the magnetic parameters of an object using stationary and mobile magnetogradient measuring systems built using scalar and vector magnetically sensitive sensors of various types, as well as various gradient installation designs.
Keywords:magnetic field of an object, remote magnetogradient measurements, vector and tensor magnetogradientometers.
