摘要
介绍一种基于虚拟仪器技术的弹丸初速测量系统 ,阐明系统工作原理、实现方法及系统的硬件和软件结构 ;利用小波变换空间局部化性质 ,探讨小波变换模极大值检测信号突变点的方法在确定天幕靶弹丸信号特征点的应用 ,大量实验表明了该系统的可行性及实用性。
A measurement system was introduced about initial speed of projectiles based on virtual instrument technology.It stated the operating principle,method of implementation,the hardware and software structure.The wavelet transform was used to perform local analysis in space,and an abrupt change could be detected by model maximum of wavelet transform,the feature point of signal was gotten when projectile passed through sky screen optical target.Experiments proved the feasibility and practicability of the system.
