Description

Technical Field

[0001] This utility model relates to the field of electromagnetic exploration technology, specifically a wide-area electromagnetic instrument receiver. Background Technology

[0002] Wide-area electromagnetic sounders operate based on the principle of electromagnetic induction. They transmit electromagnetic waves of a certain frequency into the ground and then receive the returning waves. By analyzing the amplitude, phase, and other information of the received electromagnetic wave signals, they infer the underground structure and materials. The electromagnetic wave signal receiver is a core component of the wide-area electromagnetic sounder, and its performance directly affects the instrument's detection sensitivity and resolution. Currently, most wide-area electromagnetic sounders use superheterodyne receivers, which have advantages such as high sensitivity and strong anti-interference capabilities.

[0003] During testing, the testing personnel record the electromagnetic wave data of the current area using a portable wide-area electromagnetic instrument receiver. After recording, they change areas and test again. The wide-area electromagnetic instrument receiver has a box-like casing, which is not easy to place in areas with large terrain undulations and is prone to being bumped. Carrying a stand is troublesome because the three legs of the stand need to be repositioned after moving. The stand itself is also large and not easy to carry. At the same time, the testing personnel have to squat down and bend over to observe the data, which is inconvenient. Therefore, we propose a wide-area electromagnetic instrument receiver.
