Abstract
In the underwater objects passive detection
high sensitivity
low-frequency vector hydrophone with excellent performance is needed.The traditional vector hydrophone can’t match these demands
so much research of vector hydrophone based on new theory is done.A novel MEMS vector hydrophone is presented
the azimuth detection theory of vector hydrophone is introduced.The direction-of-arrival estimation experiment is designed
the experiment is conducted.The test result shows that the test value may agree well with the actual value
