| 摘 要： | 用超声波确定方向是一种自然现象,其测向的原理实质是由接收器间声波信号的相位差确定。依据实验效果,该文提出了用两个接收器提取信号相位差并进行角度指示的方案,讨论了模拟信号处理中的一些技术问题。这一方案特别适用于小型运动物体方向角的动态测量和自动跟踪装置。

| Abstract: | Using ultrasonic wave to determine the direction is one kind of natural phenomenon,Its principle is essencely determined by phase difference between the sound wave of the receivers.This article put forward a scheme which used two receivers to withdraw the signal phase difference and to carry on the instruction of the angle,and discussed some technical questions in the processing of analog signals.This plan is specially suitable for dynamic measurements and the automatic tracking devices of direction of angle of small moving objects. |
