为了提高固体速度测量精度,提供一种基于独立成分分析(ICA)处理两相流信号的基本方法。首先介绍独立成分分析(ICA)的基本原理,然后介绍使用空间滤波和小波变换获得固体速度的方法。最后给出仿真实验结果证明该方法可行。
In order to improve the accuracy of solid-state velocity measurement, a basic method of processing two-phase flow signals based on Independent Component Analysis (ICA) is provided. First introduce the basic principle of independent component analysis (ICA), and then introduce the use of spatial filtering and wavelet transform to obtain the solid velocity method. Finally, the simulation results show that this method is feasible.
