摘要

提出了一种应用于直接序列扩频(DSSS)高精度超声距离测量的多普勒效应补偿技术。本文首先阐述了多普勒补偿技术的原理，然后讨论了m序列编码超声信号的实验结果。评估结果表明，该方法可以在0.1 ~ 1.6 m范围内测量以2m /s速度运动的目标距离，效率大于95%，且采用128位或32位长的DSSS码，标准偏差小于8 mm。

Doppler shift compensation technique for ultrasonic DSSS ranging system

We present a Doppler effect compensation technique that can be applied to high-precision ultrasonic distance measurement using the direct sequence spread spectrum (DSSS). In this study, first, the theory of Doppler compensation technique is explained, and then the experimental results using the M-sequence coded ultrasonic signals are discussed. The evaluation results show that the proposed method can measure distance of target moving at 2 m/s in the range of 0.1–1.6 m, with an efficiency of more than 95%, and with a standard deviation of less than 8 mm by using either a 128-bit or a 32-bit long DSSS code.
