Study of properties of real vibroseis signals contaminated by harmonic noise
Properties of the ground force signal complicated by harmonics are studied. It is shown that the adaptation filters, that enable matching the amplitude- and phase- frequency characteristics of harmonics in the corresponding frequency range, have a simple form. The problem of focusing a signal containing harmonics using correlation and deconvolution is discussed. An example of using harmonics to expand the signal spectrum is given.
