摘要
时-频联合分析法是近年来才兴起的一种信号分析方法,它是分析处理频率随时间而改变的非稳态信号的强有力工具。本文对这种方法作了简单介绍,并采用这种方法处理了嵊山海洋站海水表层盐度观测资料。所得结果表明,这种方法与传统方法相结合可以更好地分析海洋观测数据。
The newly emerged JTFA ( Joint Time-Frequency Analysis ) method is a powerful tool for analyzing time-varying non-stationary signals. In this paper, we introduce this method briefly and apply its techniques to the processing of salinity data. The results show that this method combined with traditional methods can help us to get a better analysis of ocean observations.
