MEMS vector hydrophone can not only measure sound pressure signal
but also particle velocity signal.It has nothing to do with the frequency of dipole natural directivity.Single vector hydrophone can measure sound pressure and particle velocity in the water.Using this characteristics
acoustic orientation system is designed based on MEMS bionic vector hydrophone combining with beam forming principle and DSP technology.Results of actual tests show that this system can realize orientation function of 360°direction for target.
