Abstract
The matched-field processing (MFP) method has been substantially applied for source localization studies in recent years. It has been demonstrated that the MFP is very sensitive to the mismatch of sound-speed profile (SSP) with a high-resolution MFP estimator. It turns out that the high-resolution MFP is also a potential powerful tool for SSP inverting with a known source-receiver system [A. Tolstoy and O. Diachok, J. Acoust. Soc. Am. Suppl. 1 88, S117 (1990)]. In this paper, the high-resolution mode matching (HRMM) estimator [E. C. Shang, J. Acoust. Soc. Am. 86, 1960 (1989)] has been used for El Niño profile inverting. By matching a proper set of modal travel time perturbation, the El Niño profile can be efficiently inverted in a 2-D parameter space based on a simple acoustic model of the 1982-1983 El Niño event.
