  • Experiment:
    • Location: Off the coast of Kochi Prefecture
    • Date recorded: July 2022
    • Center frequency: 6 kHz
    • Bandwidth: 4 kHz
    • Symbol rate: R = 4 kHz
    • Distance: 14 km
    • Tx/Rx/water depth: 176 m/146 m/x. The data contain down-slop, up-slope and flat. The water depth in the flat scenario is 200 m.
    • Mobility: moored
    • Receiving array: vertical, up to 24 elements. There are six hydrophone groups. Within each group, the inter-element spacing is 0.9 m. The distance between groups is 1.8 m.
  • Parameters:
    • Sampling rate in delay: 2R
    • Total delay coverage: up to 117.5 ms
    • Sampling rate in time: R/100 for the channel response, 2R for the phase/delay
    • Total time coverage: 1 minute
