“…Matched-filter output from these phones was equally successful in extracting the various boundary echoes and preliminary model runs (Figure 16) show that the arrivals for phones in deeper parts of the range are also well modeled. The paper by Lewis, et al [4] in this volume discusses these data in greater detail.…”

FIGURE 1. Multi-beam echo sound survey of the site and location relative to the island of Kauai (inset). FIGURE 2. Equipment lay down for KauaiEx. The principal sound source located at the southern end (left) broadcast to VLA' s distributed along the track. Acoustic sensors were interleaved with environmental sensors including thermistor strings along the entire propagation path. FIGURE 4. Deployment of the telesonar testbed (left). Track of the towed transmitter (T1) relative to the receiver testbed (T3) (right). FIGURE 5. Matched-filter response or replica correlogram showing the impulse response of the channel in 3 separate frequency bands.
