Description

technical field [0001] The invention relates to an aerial magnetic field detection system and method of an unmanned aerial vehicle, belonging to the technical field of new aerial geophysical prospecting instruments. Background technique [0002] Magnetic prospecting is a geophysical prospecting method that studies the distribution of geological structures and mineral resources (or other detection objects) by observing and analyzing magnetic anomalies caused by magnetic differences in rocks and ores (or other detection objects). Can be used in all stages of geological surveys. Applications in regional geological surveys include: ① Carry out tectonic division, study deep and large faults, determine contact zone, fault zone, fracture zone and basement structure; ② divide the distribution range of sedimentary rock, intrusive rock, extrusive rock and metamorphic rock, Carry out regional geological mapping; ③ study the formation and distribution of regional minerals. The applica...
