碩士 === 國立交通大學 === 電機資訊國際學程 === 107 === To date, low-cost high-performance ultrasonic range finders remain a significant role
in both domestic and industrial applications. In these systems, distance measurements are
based on determining the time-of-flight (TOF) of reflected echoes in a pulse-echo
configuration.
In this work, our first goal is to investigate circuit techniques and digital signal
processing algorithms to improve the range and resolution of a proposed ultrasonic range
finder. In addition, from the results of this system, we will explore a design of ultrasonic
interface integrated sub-circuits toward noise reduction and compactness.
An experimental circuitry being constructed to operate with 100kHz transducers is
capable of detecting a distance within the range of 3m with a resolution of 0.1m (or 100mm).
From these references, a combination of ultrasonic interface integrated sub-circuits was
simulated. This circuit can achieve a peak Signal-to-Noise-and-Distortion Ratio (SINAD) of
80dB.
