| description | Due to the pressing demand for metallic ore exploration technology in
China, several new technologies are being employed in the relevant
exploration instruments. In addition to possessing the high resolution of the
traditional transient electromagnetic method, high-efficiency
measurements, and a short measurement time, the multichannel transient electromagnetic method (MTEM)
technology can also sensitively determine the characteristics of a
low-resistivity geologic body, without being affected by the terrain.
Besides, the MTEM technology also solves the critical, existing interference
problem in electrical exploration technology. This study develops a
full-waveform voltage and current recording device for MTEM transmitters.
After continuous acquisition and storage of the large, pseudo-random current
signals emitted by the MTEM transmitter, these signals are then convoluted
with the signals collected by the receiver to obtain the earth's impulse
response. In this paper, the overall design of the full-waveform recording
apparatus, including the hardware and upper-computer software designs, the
software interface display, and the results of field test, is discussed in
detail. |
