SeaSonde
The SeaSonde is an operating in HF-Band multistatic Over-The-Horizon radar designed to measure local surface windspeeds and wave directions.
The single radar consists of an approximately 7 m long dipole antenna and 19 inch rack frames for receiver and transmitter. Using very low frequencies (5 MHz), an additional transmitter antenna is needed, that is placed at a distance of about 100 … 150 m of the receiver antenne. At least two SeaSonde radars are normally required for creating 2-D surface current maps of direction and speed. The recommended maximum distance between adjacent radars is 40 … 60% of the radar's offshore range.
