设计了一种用于速度测量的连续可变延时相关器。上游和下游检测器之间的逆渡越时间（速度）由反馈回路连续调节，该反馈回路在距离峰值相关的两个相等间隔处保持互相关水平恒定。通过改变控制数字移位寄存器延迟线的时钟频率来实现可变延迟。该系统的输出是线性的，与并行逻辑互相关计算机的计算结果一致。
A continuously variable time delay correlator was designed for the purpose of measuring velocity. The inverse transit time (velocity) between upstream and downstream detectors is continuously adjusted by a feedback loop which maintains constant the level of cross correlation at two equal intervals from the peak correlation. Variable delay is achieved by changing the clock frequency which controls a digital shift register delay line. The output of the system is linear and identical to that calculated with parallel logic cross correlation computers.
