| Abstract: | The limited angle of sensing can restrain ultrasonic sensor's wide application in locating the moving objects and in guided system.Basing on analyzing the ultrasonic transmission process and the influence of off-axis ultrasonic wave,the design method for relevant circuits and the sensor array based on-3dB angle of the sensor was put forward and many experiments for it were implemented simultaneously.The experimental results show that,in the premise of no ultrasonic waveform is affected,this design can expan... |
