Directivity Study of Dual Source Single Enclosure Ultrasonic Parking Sensors
碩士 === 國立臺灣大學 === 應用力學研究所 === 97 === Ultrasonic sensors have been used widely to generate higher directional radiating patterns where piezoelectric units are sparsely distributed in space. In this study, we present a novel design of a phase array ultrasonic sensor based on the concept of vibration d...
