摘要
用基于微机PCI总线的A／D采集板实时采集光幕靶的输出信号，采用数字信号处理的方法实现弹丸速度的测量，滤出干扰信号，增加测量可靠性。通过相关试验数据，分析了相应参数对测速精度的影响。
A method for measuring the velocity of flying bullet is described, with which the output signal of the optical screen target is acquired in real time with A/D board based on PCI bus. The velocity of bullet is measured with DSP method ,while signal is filtered, to enhance the reliability of the measurement. The influence of relevant parameters on the interference accuracy is analyzed.
