Abstract

The invention relates to the technical field of magnetic measurement in geophysical exploration, in particular to a backpack type magnetic gradient measurement system. With the system adopted, ground magnetic gradient measurement to be realized in a backpack mode, all functional modules of magnetic gradient measurement are integrated, independence and convenience are achieved, and a magnetic measurement scanning area is greatly widened. The system has three working modes, namely horizontal gradient measurement, vertical gradient measurement and longitudinal gradient measurement; the system is powered by a high-capacity lithium battery, the single endurance time is longer than 12 hours, and the actual operation requirement in the whole daytime is met; and all the functions of the system meet the ground magnetic measurement requirements, the performance is stable and reliable, and the operation modes of ground magnetic gradient measurement are extended.

Description

technical field [0001] The invention relates to the technical field of magnetic measurement in geophysical surveying, in particular to a piggyback magnetic gradient measurement system. Background technique [0002] Magnetic measurement is one of the most widely used methods in magnetic geological survey in the field of geophysics. It can reliably reflect the magnetic anomalies on the surface or in the detection area. Through continuous scanning, recording and storage of the survey area, and according to the obtained Through the processing, inversion and mapping of the geomagnetic observation data, the magnetic anomaly profiles with different characteristics can be obtained. By analyzing the magnetic anomaly profiles and combining the geological magnetic field characteristics, it is possible to realize deep geological structure analysis and bury magnetic bodies. Therefore, magnetic measurement is widely used in surface exploration, geological prospecting, underground buried o...
