An Underwater Acoustic Vector Sensor with High Sensitivity and Broad Band

An Underwater Acoustic Vector Sensor with High Sensitivity and Broad Band

Recently, acoustic vector sensor that use accelerators as sensing elements are widely used in underwater acoustic engineering, but the sensitivity of which at low frequency band is usually lower than -220 dB. In this paper, using a piezoelectric trilaminar optimized low frequency sensing element, we...
