A Study of the Techniques for Large-depth and Multi-functional Electromagnetic Survey
大深度多功能电磁探测技术研究

Based on a study of the high-power and multi-functional launching system of the electromagnetic method and its corresponding key technologies; the authors developed a high-power (70 kw) and multi-functional (with the power supply function of CSAMT and IP) intelligent transmitting prototype that has independent intellectual property rights. Accordingly, the multi-functional (with the measurement function of AMT, CSAMT and IP) receiving prototype was also designed and developed. As a result, the matched data processing technology of the multi-functional electromagnetic system has been successfully resolved. A comparative trail was carried out between the self-developed multi-functional electrical system and the GDP32 system, with some good results achieved.
