A hardware circuit design characterized by differential-receiving,double-gated and peak-keeping is proposed for the long tail of detection signals and the low resolution of ultrasonic signals caused by redundancy capacitors existing in the analog board.Flaw signals are selected from the full-wave signal by designing a gate-select circuit in front of the detecting circuit to remove the tail of detection signal effectively and improve the reliability of ultrasonic signal.This article introduces the adjustment of receiving circuit in terms of hardware.The experiment shows the system has stable performance,high precision,and large range,and with a broad application prospect.

Key words: receive and dispatch of ultrasonic;differential receiver;double gated;high precision
