- 10. Applications Aviation, Terminal Area Weather Support • Wind profilers are extremely well suited to provide high temporal and spatial upper-air data for airports that are affected by complex terrain. These systems are used to monitor the upper level flow above the terminal area in support of wind shear and turbulence monitoring
- 11. Doppler Beam Swinging (DBS) • Radial scattered velocities measured with one vertical and 2 (4) off-zenith beams • Beam-pointing sequence is repeated every 1-5 minutes • Local horizontal uniformity of the wind field is assumed • Signal processing involves: – coherent integration of the complex video signal – spectral analysis – incoherent integration – isolation of signal spectrum from noise spectrum – velocity calculation and temporal averaging of radial velocities – calculation of wind profiles

- 14. CLC-11 wind profiler Features 3 Active phased array antenna Employing active phased array antenna enables us to measure the wind profiles every one minute with its high-speed beam scanning capability. And it assures us that stable and accurate measurements are carried out even under high winds such as typhoons, that were unattainable by radars using conventional reflector type antennas. Pulse compression technique Employing the 16-bits pulse compression technique resulting in the improvement of 12dB of the received echo signal to noise ratio (S/N) compared to single pulse radars, enables us to measure winds at high altitudes.

- 17. Antenna • Electrically switched phase delays between the micro-patch antenna elements change the pointing direction. • Each of the planar panels is protected from direct exposure by integral radome. • The antenna used active phased array technique and consists of planar micro-patch array panels with a sidelobe reduction screen. • The antenna panels are oriented horizontally while the antenna beams point to four orthogonal oblique directions as well as to zenith.

- 19. Optional RASS • Radio Acoustic Sounding System (RASS) – provides profiles of temperature – achieved by transmitting a strong but short acoustic "beep" vertically upwards – tone burst travels as a compression wave with the speed of sound upwards in the atmosphere – wind profiler measures the speed of propagation of the sound burst – since the speed of sound depends on the air temperature, virtual temperature can be computed from the received signal
