Abstract : Examining Intimate'96 hydrophone data (300-800 Hz) we see clearly the effects of tidal changes, i.e., of changing water depths. In this work we will examine Matched Field Processing (MFP) sensitivity at the range of frequencies to expected tidal changes (the depths vary +-1 m from the nominal of 135m). Is it possible to invert such data to accurately and uniquely estimate water depth D as a function of time (tides) ? What about accurate, unique estimates of source range r ? What happens when we use multiple frequencies and when D is known to shift in a predictable fashion ? Can the r vs. D ever be resolved for a successful, unique MFP for those parameters ?
