In this shallow-water experiment a source was towed at midchannel depth to a range of 6 km from a vertical line array. The source simultaneously hummed four tones with pitches from 50 to 600 Hz. Using the matched-field approach, an acoustic model was used to scan a beam through range and depth in the channel. It is shown that the source can be tracked continuously by combining the data from all four frequencies.
