Abstract
The classical higher order spectra (HOS) have been widely investigated [1-7] for stationary processes. However, for some important practical applications in radar, sonar and mechanical systems (e.g. change of the instantaneous frequency of radar and sonar signals, change of the shaft frequency during machinery operation etc.), it is necessary to process non-stationary signals with frequency non-stationarities. The classical techniques are not suitable for those signals because the HOS average a non-stationary frequency and thus create estimation errors due to frequency nonstationarity.
