Abstract: Measuring non-stationary level is an important topic in non-stationary signal processing.Although the existing measurement parameters and methods have obvious differences in principle and are not derived from a unified theoretical framework and metrics,these measurements play an important role in the corresponding fields.This paper summarizes the measurement parameters and methods for the non-stationary signals in different research fields systematically,including the statistic and dynamic parameters in time domain,the parameters in time-frequency domain,signal modeling parameters and specific non-stationary signal measurements.Moreover,the applications of various measurement parameters and methods are given briefly.Finally,the future work on the non-stationary signal measurements is also deduced.
