FIELD: physics.
SUBSTANCE: device contains a transmitting part and a receiving part. The transmitting part includes a sequentially coupled high voltage power supply, a probe driver, and a transmit antenna, and the receiving part - a sequential coupled receiving antenna, a signal processing means, and a means for presenting the results of the signal processing. The signal processing means comprises a two-channel analog-to-digital converter, the outputs of which are connected to the inputs of the converter signal combining means for the transmission of the processing results to the presenting means.
EFFECT: expanding the range of the processed values of signals coming in response to the feeding of probing pulses, which allows to receive information without distortions from different probing depths, practically excluding distortions related to the nonlinearity of the input characteristics of the receiving elements.
