Study on improving MCSEM signal-to-noise ratio
提高海洋可控源电磁法信噪比的方法研究

Marine controlled-source electromagnetic(MCSEM) data processing techniques have been developed fast in the past few years. We make a study on how to reduce the noise of MCSEM electrical dipole-dipole with simulated data processing while the noise contained in the raw data will be negative on the data interpretation. Two methods which were concluded by the author are introduced here: time domain filtering and noise estimation. It is proved that these methods are valid and time domain filtering and noise estimation can reduce the ambient noise, and increase the signal-to-noise ratio.
