Green

A 6 kHz single-hydrophone channel from a Norwegian fjord (Norway'24), providing time-diversity data from repeated transmissions over a 270 m range.

Experiment:
- Location: 60N, 5.3E
- Date recorded: November 2024
- Center frequency: f_c = 6 kHz
- Bandwidth: B = 4.5 kHz
- Symbol rate: R = 4.5 ksym/s
- Distance: d = 270 m
- Tx/Rx/water depth: d_T/d_R/d_w = 20 m/43 m/60 m
- Mobility: moored
- Receiving array: none (single hydrophone)
- Time diversity: M = 64 channels formed from transmissions repeated every 10 minutes
Parameters:
- Sampling rate in delay: f_s = 2R
- Total delay coverage: up to 400 ms
- Sampling rate in time: R/1000 for the channel response, 2R for the phase/delay
- Total time coverage: approximately 55 seconds
