The results demonstrated that this technology can improve imaging of coal seams in structure complicated areas and coalfield seismic data signal-to-noiseperformance and resolution effectively.
Compared with DC coupling signal processing, it need lower requirement of signal processing circuit and have the merit of high signal-to-noiseperformance although it require the device of modem.
The experiment results show that the new technique outperforms the conventional spectral subtraction methods in spectrogram characteristic, output signal-to-noise ratio (SNR) and aural performance.
