基于非均匀间隔采样的光幕过靶信号波形获取
摘要
Abstract
In order to ensure the measurement precision of the light screen array,a signal waveform acquisition method based on non-uniform sampling is proposed.Firstly,the signal characteristics of the light screen passing through the target projectile are analyzed,and it is concluded that the signal has the characteristics of transient,aperiodic and large frequency bandwidth.Secondly,the principle of non-uniform fractional sampling is described.Then,the corresponding signal acquisition system is designed and its working principle is introduced.Finally,experiments show that,compared with the traditional method,the measurement precision of the system meets the requirements,and the measurement cost can be reduced at the same time.关键词
