- Statement
- A swept-frequency ("chirp") transmission pulse was used, which required the return signals to be cross-correlated with the source signature (matched filter) throughout the cruise to extract signals with a simple effective waveform, which also has the benefit of reducing random noise (see more information in the cruise report: https://www.bodc.ac.uk/resources/inventories/cruise_inventory/reports/jr298.pdf )
