超音波測位システムの送受信信号の減衰による距離測定誤差の改善

抄録

We have been developed in ultrasonic positioning system that can get the position of target object in real time measurement. In the distance measurement experiment, it includes the measurement error by receiver signal attenuation for speaker’s directivity. To aim for improvement of measurement accuracy, this study introduces a correction formula for the receiver signal arrival time measurement.
