Abstract
An electromagnetic geophysical exploration system includes a first transmitter configured to transmit a first waveform in a first spectrum, a first receiver configured to sense signals in the first spectrum, a second transmitter configured to transmit a second waveform in a second spectrum, the second spectrum having a frequency higher than a frequency of the first spectrum, a second receiver configured to sense signals in the second spectrum, the second receiver configured to be minimum-coupled to the second transmitter, wherein a transmitter coil of the second transmitter is disposed between an inner receiver coil and an outer receiver coil of the second receiver, and the inner receiver coil and the outer receiver coil of the second receiver surround the transmitter coil of the second transmitter, and a control portion configured to control the first transmitter and the second transmitter.
