Abstract

The goal of this paper is to evaluate the effectiveness of a selection of low-cost sonar systems as applied to autonomous underwater navigation. The systems in question are a phased array, an inverse triangulation-based array, and a set of dipole-based arrays. These systems are based off of low-cost audio processing hardware, representing a significant cost reduction over existing industry solutions. The systems are evaluated against the criteria of price, positional accuracy, and hardware/software simplicity. These initial tests only evaluated the bearing accuracy of the system, ranging was not assessed at this stage. All of the systems were evaluated in an above-water field test and their performance compared.
