Mixed Vibration Signal Separation and Moving Object Detection Based on Independent Component Analysis
Ning Qiang, Xiang Zhong Fang · Advanced materials research · 2011
This article briefly describes the basic theory of independent component analysis (ICA) and algorithms. Independent component analysis (ICA) method is employed to separate the mixed vibration signal, measured from linear sensor array. By calculating the spatial spectrum function, identification and tracking of multiple moving targets achieved. The results show that, ICA can successfully detect and track multiple targets.
