The triangular geometry of the sensor is converted to orthogonal coordinates to achieve the x and y components. Then the sensor converts the wind vectors into polar coordinates.
The measurement results are reported as follows:
- WMT700 reports WS (x, y)
as 2 scalar speeds, one parallel to the N-S direction (x) and the other (y) parallel
to the W-E direction.
x = -WS × cos (WD) y = -WS × sin (WD)
- WMT700 reports polar wind speed as a scalar speed in selected units (m/s, kt, mph, km/h).
Polar wind direction is expressed in degrees (°). WMT700 indicates the direction that the wind comes from. North is represented as 0°, East as 90°, South as 180°, and West as 270°.
