Description

technical field [0001] The invention relates to an optimization modeling method of magnetic shielding tube parameters of an atomic magnetometer / atomic gyroscope based on shielding coefficients (axial shielding coefficients and radial shielding coefficients), which belongs to weak magnetic detection and navigation positioning technology. Background technique [0002] The atomic magnetometer / atomic gyroscope has become a project developed by foreign military powers because of its ultra-high theoretical sensitivity and ultra-high precision. The atomic magnetometer / atomic gyroscope is a magnetic field / inertial measurement device that works in a weak magnetic environment based on ultra-fine energy level atomic transitions. The magnetic shielding cylinder of the atomic magnetometer / atomic gyroscope can shield the external stray magnetic field. Therefore, strict requirements are put forward for the shielding performance of the magnetic shielding cylinder made of high magnetic perme...
