abstract. With the enhanced capabilities of the TIGER-3 platform, and a vastly superior signal to noise ratio, the latest TIGER transceivers have the potential to be utilised effectively to study sea-state conditions, in addition to regular SuperDARN operations. A circular design allows great flexibility in the use of the system. For instance the RADAR could provide 3 or more beams from a central east coast location, (ie. Effectively 3 or more radars) with one beam looking poleward overlapping the FoV of the current RADARs, one beam looking equatorward to monitor low latitude activity, and a third beam looking eastward over the Pacific Ocean.
The operation of the RADAR with the enhanced sensitivity would allow common mode operations to be interspersed with the sea-state measurements in a versatile operational sequence.
