在雷达、超声波、声学和其他领域中,一个常见的问题是确定两个信号之间的延迟。在许多情况下,可以确定采样信号的延迟,其精度优于采样周期。本文比较了估计这种子样本延迟的几种方法,特别注意了周期信号的情况。作者还提出了两种方法,在某些情况下比以前的方法表现得更好。
A common problem in radar, ultrasound, acoustic and other fields is that of determining the delay between two signals. In many situations, it is possible to determine the delay of a sampled signal to an accuracy better than the sample period. This paper presents a comparison of a number of methods of estimating this subsample delay, with special attention to the case of periodic signals. The authors also suggest two methods, which perform better than previous methods in some situations.
