小波分析在粒子特性测量中的应用
A New Method of Particle Measurement Based on the Wavelet Analysis
【摘要】 根据PDA信号的猝发性特点 ,提出了基于小波变换的PDA信号处理方法。利用小波系数表征信号的时 -频特性 ,可有效地实现PDA信号的识别和处理 ,具有明显的优越性。
【Abstract】 A new PDA signal processing method based on the continuous wavelet analysis is proposed in this paper.With the Morlet complex function,the time-frequency characteristics of PDA signal are described by the wavelet coefficients.The identification & processing can be fulfilled simultaneously.
