Abstract

Different transmission exciting pulses of ultrasonic sensor have great effect on ultrasonic transmission power

and determine ultrasonic wave detection range. The relationship between different kinds of exciting pulse and transmission power is given by analysis of power spectrum. The bipolar transmitter circuit of long-distance ultrasonic sensor is designed to adjust the number and frequency of pulse. The type

number

excitation voltage of ultrasonic exciting pulse are determined via experimental studies. The circuit has been successfully used in longdistance ultrasonic ranging system

and can reliably and stably detect the obstacles with the distance about 25 m.
