Abstract
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.
