Abstract
Matched field processing (MFP) is appliable to localize tonal sources with arrays and sensitive to the environment mismatch. To localize a broadband source with one hydrophone in shallow water, a new method utilizing frequency-difference autoproduct is proposed in this paper Simulations have been conducted to evaluate the performance of the method. A sea trial data from the SACLAT experiment (1993) is also used to validate it. Comparing to MFP with one hydrophone’s magnitude-only data, the new method is more robust to the environment and has a higher success rate of source localization.
