The Experimental Data Analysis of Vector Hydrophone
The paper gives out the calibration method of the sensitivity and phase to a vector hydrophone; it analysed the data from the lake trial and the sea trial. The results indicate that, in the isotropic noise field, the sound pressure and the velocity are not related, but the signals are completely relevant. When there is no coherent interference, both the average sound intensity device and the diagram of the target orientation estimation can efficiently estimate the target orientation; when there is the interference of a strong line spectrum, the average sound intensity device cannot work properly, but the diagram can still effectively estimate the target position; when the target radiates spectrum, the line spectrum of the target orientation estimation can still have very good performance.
