Research On The Planar Integration Vector Hydrophone

The vector hydrophone sensitive by the principle basically piezoelectric principle, and also have electric principle of the magnetoelectric type vector hydrophone. The form have the differential pressure, vibration type and several, Such as moving coil type vector hydrophone, cantilever beam pumping vibration sensor, piezoelectric multidimensional measurement with strikeout disc bending type, intermediate frequency vector hydrophone three-dimensional spherical vector hydrophone.At present, the overall level is quite with France. But on the equipment is currently in test application stage, many engineering application problems being solved. Vector hydrophone appear to make sonar information is obtained from original greatly increased, the only measure scalar information, the transition to the sound field vector information measurable, these information of sonar signal Profit of sonar signal processing。This paper based on the above technology using piezoresistive principle, piezoelectric principle of making two principle respectively vector hydrophone. Using hybrid integrated technology, will the preamplifier circuit and sensitive core body integration to a small volume, Make the whole sensor reduced volume, improve sensor can use frequency response bandwidth. Based on the two principle of vector hydrophone design, production and testing, The principle analysis of two underwater sensor, summarizes the characteristics and advantages of the vector hydrophone design experience.
