Magnetic target localization method based on mobile platform

Abstract

Aiming at the problem that the calculation process of magnetic target localization is complex and greatly affected by the geomagnetic field, a single-point magnetic gradient tensor localization method is derived differentially, and a target localization method based on a third-order tensor of plane cross structure is proposed. The positioning method can locate the magnetic target in real time based on the mobile platform, theoretically can reduce the influence of the geomagnetic field on the target positioning, and the calculation process is simple, and there is no need to solve the nonlinear equation system. The effectiveness of the localization method is verified by simulation, and the influence of the baseline of the tensor measurement system on the localization results is verified.
