Characteristics of 3-D Underwater Object Recognition Independent of Translation Using Ultrasonic Sensor Fabricated with Porous Piezoelectric Resonator

다공질 압전소자로 제작한 초음파 센서의 물체변위에 무관한 3차원 수중 물체인식 특성

In this study Characteristics of 3-D underwater object recognition independent of translation using the self-made ultrasonic sensor fabricated with porous piezoelectric resonator and presented. The sensor was satisfied with requirement of ultrasonic sensor. The recognition rates for the training data and the testing data are 97.45 and 91.25[%] respectively using the self-made ultrasonic sensor and SCL(Simple Competitive Learning) neural network. According to the experimental results It is believed that the self-made ultrasonic sensor can be applied as sensor of SONAR system.
