Analysis of Location Accuracy and Passive Acoustic Location with Dual Solid-symmetric Square Arrays with Four-element

摘要

The paper analyzes several methods of target location arid presents a method of acoustic target location with dual solid-symmetric square arrays with four-element. It uses two individual solid-symmetric square arrays to locate because of the high directional performance of the individual array. It eliminates the locating precision error caused by variation of sound velocity so the directional performance is improved. The emulational results show that the method has a good locating performance.
