摘要

Present invention provides an improved ultrasonic receiving unit for ultrasonic distance measurement. The ultrasonic receiving features a high peak detection unit 120, a low peak detection unit 125, an arrival time adjustment unit 130. With those features, detection error caused by single threshold could be eliminated.
