Abstract

The present invention provides a method for acquiring an aeronautic superconducting full tensor magnetic compensation coefficient, a terminal and a storage medium. The method comprises the following steps: an approximate value of a magnetic compensation coefficient of a plane gradiometer with respect to eddy current interference is acquired based on dynamic measured data, and a constraint range ofthe magnetic compensation coefficient of the plane gradiometer with respect to the eddy current interference is acquired based on the approximate value of the magnetic compensation coefficient; whenan aircraft carries a built-in aeronautic superconducting full tensor magnetic gradient measuring system for high altitude maneuvering flight, measured values of a magnetic gradient and a triaxial magnetic-field component output by the aeronautic superconducting full tensor magnetic gradient measuring system are acquired; the constraint range of the magnetic compensation coefficient of the plane gradiometer with respect to the eddy current interference is taken as a constraint condition, and the measured values of the magnetic gradient and the triaxial magnetic-field component are substitutedinto a magnetic compensation model with the constraint condition, thereby an optimal value of the aeronautic superconducting full tensor magnetic compensation coefficient is acquired. The invention solves the problem that an existing method cannot acquire the optimal solution of the aeronautic superconducting full tensor magnetic compensation coefficient.

Description

technical field [0001] The invention belongs to the field of aeromagnetic measurement, and in particular relates to a method, a terminal and a storage medium for obtaining a full tensor magnetic compensation coefficient of aeronautical superconductivity. Background technique [0002] The full tensor magnetic gradient describes the rate of change of the magnetic field vector in three-dimensional space, that is, the gradients of the three components of the magnetic field vector in three directions in space. The measurement results of the full tensor magnetic gradient have the advantages of being less affected by the magnetization direction, reflecting the vector magnetic moment information of the target body, and better inverting the field source parameters (azimuth, magnetic moment, etc.) Perform positioning and tracking to improve the resolution of the magnetic source body. The measurement and interpretation of the full tensor magnetic gradient is regarded as a major breakt...
