Design of Passive Acoustic Location System Based on Double Arrays

Abstract

The biggest advantage passive acoustic positioning system based on single array is that it has high performance on orientation. However, its positioning error is usually larger. Locating based on multi-array not only gives more information to enhance the locating accurate, but also can eliminate the blind area generated by single array. So its locating performance is better than single-base array. In this paper, taking the system of double arrays for instance, built a passive acoustic positioning system, gave the plan of the system, and designed the tests to compare the accuracy between the single array and double arrays. According to the tests, it further verified that locating system based on double arrays has higher accuracy than the system of single array. And it also has high value engineering.
