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（如十几米／秒～几十米／秒），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。
Correlation method has been developed for many years. Due to the large computational complexity, the software implementation, for large-speed systems (such as ten meters / second to tens of meters / second), limited by the speed of operation, its real-time and accuracy are less than ideal. To this end, this article describes a way to achieve the relevant computing hardware, and hardware-related instrumentation structure and interface with the 8098 microcontroller block diagram.
