Abstract

Novel time-frequency techniques are proposed: the short time instantaneous higher-order spectra (HOS) with adjustment to measured or known a priori time variation of the instantaneous frequency of transient signals. It is shown that the proposed transforms are more effective than the non-instantaneous HOS (i.e. without adjustment to time variation of the instantaneous frequency) in recognizing a non-stationary nonlinearity.
