Radar wind profiler signal characteristics during bird migration episodes
نویسندگان
چکیده
The Gabor transform is used to investigate non-stationary wind profiler radar signals, which are frequently occurring during the seasonal bird migration. It is shown that the Gabor phase space representation contains a wealth of information and can be effectively used to separate the atmospheric signal component from the clutter. The crucial role of the dwell time as one of the primary sampling parameters of the wind profiler is discussed.

Advanced Intermittent Clutter Filtering for Radar Wind Profiler: Signal Separation through a Gabor Frame Expansion and its Statistics
A new method is presented for the suppression of intermittent clutter echoes in radar wind profilers. This clutter type is a significant problem during the seasonal bird migration and often results in large discrepancies between profiler wind measurements and independent reference data. The technique presented makes use of a discrete Gabor frame expansion of the coherently averaged time series ...
متن کاملQuality Assessment of Weather Radar Wind Profiles during Bird Migration
Wind profiles from an operational C-band Doppler radar have been combined with data from a bird tracking radar to assess the wind profile quality during bird migration. The weather radar wind profiles (WRWPs) are retrieved using the well-known volume velocity processing (VVP) technique. The X-band bird radar performed range–height scans perpendicular to the main migration direction and bird den...
متن کاملCombining UHF radar wind profiler and microwave radiometer for the estimation of atmospheric humidity profiles
Capabilities of an integrated ground-based system for the operational measurement of humidity profiles, using both an UHF wind profiler and a radiometer, are discussed. The combination takes advantage of the complementary characteristics of each instrument. The radiometer is able to give a fair evaluation of smoothed humidity and temperature profiles, while the wind profiler is more suited for ...
متن کاملOperation of a Mobile Wind Profiler In Severe Clutter Environments
Wind profiling radars have been in use since the 1970s (Green et al. 1979). They are now being used with increasing frequency in operational meteorology under a wide range of conditions. One limitation to operation at many sites is contamination from ground and intermittent clutter and radio frequency interference (RFI). Currently, wind profiler radars must be deployed at locations with a minim...
متن کاملLabVIEW 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 bea...
