矢量水听器信号调理电路设计
Design of Signal Preconditioning Circuit for Vector Hydrophone
摘要
Abstract
The three-dimensional vibration vector hydrophone which use ICP piezoelectric accelerometer and piezoelec -tric ceramic ring sound intensity meter as the sensitive element need constant current source as power source .And its output signal is weak ,which can not be transmitted at long range .In order to solve this problem ,a kind of signal preconditioning circuit for vector hydrophone is designed in this paper ,which contains constant-current source ,one order RC high pass filter (HPF) ,instrument amplifier and two order Butterworth low pass filter (LPF) .Then the test circuit is fabricated and the performance test is carried out .The test results show that the vector hydrophone can be powered and its original signal can be amplified and filtered by this signal preconditioning circuit ,which means that this signal preconditioning circuit can meet the demand of working with the vector hydrophone .关键词
