A Versatile Ultrasonic Ranging System

Abstract

Pulse‐echo methods as used for distance measurements are generally based on the determination of the time of flight between a transmitted pulse and its echo. It is quite easy to measure the exact moment of pulse transmission. However, the moment of arrival is difficult to measure with high accuracy because of interference and noise.
