Research on Passive Acoustic Localization with Array Field and Its Accuracy Analysis
A passive acoustic localization method is proposed to estimate the position and bearing of a moving target whose acoustic energy emissions are received by a ground-based array field. The basic array of this array field is a particular type of planar array consisting of two orthogonally orientated linear subarrays with a common sensor at the center. This technology overcomes the ambiguity of linear array localization. We also discuss error factors related to the localization. In contrast to other array configuration, the configuration we proposed is simple and fast in computation and has high accuracy in estimating target range and bearing.
