摘要

匹配域处理(MFP)适用于带阵列的调频源定位，对环境不匹配敏感。为了实现单水听器在浅水环境中的宽带源定位，本文提出了一种利用频差自积定位的新方法。SACLAT试验(1993年)的海上试验数据也被用来证实它。与单水听器震级数据的MFP相比，该方法对环境的鲁棒性更强，源定位成功率更高。

Frequency-Difference Matched Field Processing for Broadband Source Localization With One Hydrophone in Shallow Ocean Environment

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.
