•The phased array transmits signals with a light time delay from one side to the other across the creates a beam of radiation pointing in a specific direction.
•By using several beams, the profiler can measure the vertical profile of the wind (speed and direction).
•The wind profiler is another type of Doppler radar that operates in very high frequency (VHF) or ultra high frequency (UHF).
•The profiler has a “phased array antenna” that is different from the typical dish antenna.
