摘　　要：非平稳随机信号的分析与处理是近年来新兴的重要领域。分别从自适应AR谱分析法、可化为平稳随机情况处理的非平稳随机信号的分析方法、时变参数模型法以及基于非参数模型分析的参数模型法等几个方面综述了非平稳随机信号参数模型分析方法的发展现状,评述了这一前沿领域的最新进展。最后指出了这一领域需进一步研究的有关问题。Analysis and processing of the non-stationary random signals is a research hot spot nowadays. In this paper, the analytical methods for the non-stationary random signals based on parameter models, such as adaptive AR spectral analysis, analysis of the non-stationary random signals as the stationary random signals, time-varying parameter model and parameter model based on non-parameter model analysis are studied, and the latest progress of this frontier is reviewed. At the end of the paper, some problems yet to be studied are addressed.
