Process for cancelling stationary sinusoidal noise in seismic data |
摘要 |
An improved method for cancelling a stationary sinusoid corrupting a data trace is described. The frequency of the corrupting sinusoid is determined precisely and a Wiener-Levinson least squares filter is designed, using a reference sinusoid at precisely the determined frequency and correlated with the corrupted data trace. The filter is applied to the reference trace yielding a noise estimate which can then be subtracted from the data trace.
