Abstract
WSJ-4 pseudo-random signal multifunction digital IP instrument receiver system is based on the Chinese Academy of Engi-neering, Central South University Professor He Jishan invention a frequency domain induced polarization theory of a new generation of geophysical equipment. As the same series dual-band instrument in the Geophysical sweep surface application to play a lot of advanta-ges, but it is not a good solution to the distinction between the carbonaceous rocks and ore Therefore, the device is in this case, based on the academician He 2n pseudo-random signal power law theory developed, mainly carbonaceous rocks and ore phase of different fre-quency response relationship different to be distinguished from each other. Engineering practice shows, the WSJ-4 excited electric meter receiving system can distinguish between carbonaceous rocks with mine. As the first R&D personnel, the article introduces the basic principle and method of the WSJ-4 multi-functional digital pseudo-random signal receiving system, as well as in the practice of laborato-ry test data and engineering application examples, informative illustration of the instrument the Features and application effect.
