More Information
Summary:The invention discloses an electromagnetic wave CT (Computed Tomography) weak signal processing method, which solves the problem that signals are submerged in strong environmental noise due to large attenuation of electromagnetic waves when an electromagnetic wave CT technology is used for large-span measurement or high-absorption-coefficient stratum measurement, realizes the application of the electromagnetic wave CT technology in a large hole pitch of more than 40m in a high-absorption-coefficient stratum, and improves the measurement accuracy of the high-absorption-coefficient stratum. The number of drill holes along the geological exploration line is reduced by more than half, the drilling cost is greatly reduced, and the geological exploration efficiency is improved. According to the method, multiple secrecy experiments are carried out in construction of multiple subway lines, and good effects are achieved. The application of the method disclosed by the invention is of great significance to the efficienc
