Web27 dec. 2024 · Induced polarization (IP) is a widely used geophysical exploration technique. Continuous random noise is one of the most prevalent interferences that can seriously contaminate the IP signal and distort the apparent electrical characteristics. We develop a noise separation algorithm based on deep learning to overcome this issue. WebABSTRACT A major impediment in the path toward airborne induced polarization (IP) is an effective method to quantify data from inductive sources, such as those used in airborne electromagnetic systems.

WebThis report is an update review of the induced polarization (IP) mr;thod of geophysical exploration. Since its rediscovery and first extensive field use three decades ago, the method has enjoyed increasing popularity until it is now the most widely uscd ground geophysical surveying technique employed in explor8tion for metrlllic-Iusterminerals. Induced polarization (IP) is a geophysical imaging technique used to identify the electrical chargeability of subsurface materials, such as ore. The polarization effect was originally discovered by Conrad Schlumberger when measuring the resistivity of rock.
