“…Furthermore, for underwater vehicle testing in confined environments multipath and the acoustic reverberation time are major concerns. In these confined environments the time required for an acoustic signal to decay below the noise threshold can be on the order of several tens of milliseconds [7], [8]. With these concerns in mind there exists a niche for a small, passive localization device that is able to fit within the limitations of resource constrained vehicles tested in confined environments such as swimming pools and small tanks.…”

An acoustic localization system using a linear hydrophone array is presented which has been designed to provide three dimensional positioning information relative to a signal source for testing in confined environments such as swimming pools or water tanks. The system is designed to fit within the size, power, and computational limitations of resource constrained small underwater vehicles. The feasibility of the technique was demonstrated in a confined test environment with severe multipath signals. Experimental test results in a 8 m diameter, 4.5 m deep steel tank show localization errors of less than 5% of the slant range which is comparable to commercially available systems designed for large vehicles in the open ocean.
