A multi-sensor electromagnetic (EM) system and method for measuring gradients of EM signals. The multi-sensor EM system (200) includes a frame (202); a transmitter device (210) attached to the frame and configured to generate a primary EM field; a receiver device (220) attached to the frame and configured to record a secondary EM field generated by the earth after being excited by the primary EM field; and a gradient sensor device (230) attached to the frame and configured to record a gradient of the secondary EM field. |
