Abstract

Magnetic gradient tensor detection is suitable for geological exploration, target location and many other fields. Among the commonly used magnetic gradient tensors, the third-order magnetic gradient tensor has higher resolution and can obtain more and more magnetic source information. But its stability is poor. It will lead to a large error under the condition of noise. Aiming at the above shortcomings, this paper puts forward an improved method. The approximate calculation formula of the third-order magnetic gradient tensor is analyzed and improved. It can be concluded from the simulation results that the improved method is more stable.
