| 中文摘要: |
| 相关法测量速度已经发展了多年。由于相关运算计算量很大，软件实现时，对于大速度系统，受运算速度所限，其实时性及精度都不甚理想。为此，本文介绍１种用硬件实现相关运算的方法，并给出硬件相关仪结构及与８０９８单片机的接口框图。 |
| 英文摘要: |
| Measuring velocity by correlation method has developing for years. Because of the large correlation calculations, calculating velocity is limited and real time feature and accuracy are not good for large velcity system (more than ten ~tens m/s). This paper introduces correlation calculating method with the hardware, and the constuction of hardware correlation instrument and 8098 interface block diagram are given. |
