LabVIEW Based Moment Calculation for Wind Profiler

Wind speed is a most important weather parameter to record and monitor for many applications like meteorology, shipping, aviation etc. Wind observations are very important for general (operational) aviation meteorology, and weather prediction. Wind profilers are vertically directed pulsed Doppler radars which can analyze the back scattered signals and determine the velocity of air along the beams. In pulsed Doppler radar by steering beams by 15° from zenith, the vertical and horizontal components of the air moment can be obtained. Wind profiler systems are made for frequency bands that are around 50 MHz, 400 MHz, and 1000 MHz. The bands around 50 MHz are suited for high altitude measurements. This paper presents the design of Wind Profiler and discusses the issues such as the concept of wind profiler radar, how profilers estimate the moment of horizontal wind, Doppler Beam Swinging (DBS) technique for Wind velocity measurement. LabVIEW code is generated for Signal processing and moment calculation. Keywords— Radar, Doppler effect, Bragg’s scattering,
