WSJ-4伪随机信号多功能数字化激电仪接收系统的研制及其应用

摘要

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.%介绍了WSJ-4伪随机信号多功能数字化接收系统的基本原理和实现方法，以及其在实验室的测试数据和工程实践中的应用实例，详实地阐述了该仪器的特点及应用效果。 WSJ-4伪随机信号多功能数字化激电仪接收系统是基于频率域激发极化理论的新一代物探设备。该设备主要利用碳质岩与矿石中导电矿物质成分的激发极化性质，特别是时间常数（以相位参数反映）的显著差异性反映特性来达到区分矿与非矿的目的。
