基于非均匀间隔采样的光幕过靶信号波形获取OA
为确保光幕阵列的测量精度,提出一种基于非均匀采样的过靶信号波形获取方法.首先分析光幕过靶弹丸信号特性,得出该信号具有瞬态性、非周期性、大频带宽等特性;其次,对非均匀分数采样原理进行阐述;再次,设计相应信号采集系统并介绍系统组成及其工作原理;最后,通过试验验证与传统方法相比,系统测量精度满足要求,同时可降低测量成本.
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.
