Uplift events occur at the same frequency as unusually...
Numerical modeling of magnetic moments for UXO applications
V. Sanchez, Y. Li, M. Nabighian, D. Wright
2006, Conference Paper, Proceedings of SPIE - The International Society for Optical Engineering
The surface magnetic anomaly observed in UXO clearance is mainly dipolar and, consequently, the dipole is the only magnetic moment regularly recovered in UXO applications. The dipole moment contains information about intensity of magnetization but lacks information about shape. In contrast, higher-order moments, such as quadrupole and octupole, encode asymmetry...
