Marine Radar System
Marine radar systems monitor sea state conditions like currents and waves. Various systems including CODAR, WERA and WaMOS are utilized depending on the application.
The Coastal Ocean Dynamics Applications Radar (CODAR) system measures surface ocean current velocities using the Doppler shift of reflected radio waves. The term "CODAR" is frequently used as a generic term, but is also used to refer to CODAR Ocean Sensors, a leading manufacturer of these systems. A more general term for systems that employ radar to measure ocean currents is "High Frequency (HF) Coastal Radar". The first two CODAR stations deployed on the VENUS observatory are at Westshore Coal Terminal in Tsawwassen and one at the Iona Wastewater Treatment Plant, near the Vancouver Airport. The locations of these stations were selected so that their coverage overlaps, allowing radial velocities of ocean currents in the Strait of Georgia to be resolved into "total" velocities, i.e., north-south and east-west components.
