| Outline of Final Research Achievements |
The purpose of this research is to realize an ultrasonic positioning system that can acquire the position information of moving objects in real time and in a wide range with high accuracy. In our preliminary research, we have already achieved positioning with a time interval of 30 ms, which is more than three times the performance of other related research. In this research project, we worked on expanding the measurement range.The receiving circuit of the ultrasonic positioning system was reconstructed using PSoC5LP. In addition, we constructed an phased array transmitter as a method of improving the directivity of the ultrasonic transmitter, and confirmed that the directivity can be controlled. Moreover, it was confirmed by the numerical simulation that the pointing direction can be controlled by changing the phase angle of each transmission signal.
