Near-field source localization with an underwater inflatable sonar co-prime array
Abstract
We present a near-field source localization method for use with a recently proposed inflatable array-based sonar system. The sensing system, known as the Underwater Inflatable Co-prime Sonar Array, can be easily deployed from an unmanned underwater vehicle (UUV), as it can be stored as a folded package with compact stowed dimension. This package can be detached from the UUV and it can morph into its final structural form at the destination. The co-prime sparse array configuration offers the capability to resolve a much higher number of sources as compared to a conventional uniform half-wavelength-spaced array. Using real-data measurements in a water tank with a co-prime array prototype, we demonstrate the capability of the proposed system to localize wideband acoustic sources.
