Conventional weather radar transmits high-frequency pulses from the transmitter, and only observes the intensity of echoes reflected back from raindrops. Due to recent technological advancements in signal processing, data processing, and other fields, the capability to detect echo velocity, or Doppler ...

Analysis on Mesoscale Character to Ocean-Effect Snowstorm Using Single-Doppler Radar Data利用单多普勒雷达资料做冷流暴雪的中尺度分析 基于单多普勒天气雷达资料采用EVAP方法反演风场, 并结合径向速度, 反射率因子, 自动气象站和探空风场等观测资料, 对2005年12月6～7日山东半岛一次冷流暴雪过程的中尺... 杨成芳...
Doppler radar systems have been instrumental to improve our understanding and monitoring capabilities of phenomena taking place in the low, middle, and upper atmosphere. Weather radars, wind profilers, and incoherent and coherent scatter radars implementing Doppler techniques are now used routinely both ...
power. A comprehensive treatment of pulse compression and the Doppler processing of frequency modulated signals is given. This monograph should be of value to oceanographers, meteorologists, atmospheric scientists, and radar engineers, as well as students and researchers interested in Doppler radar ...
This book reviews the principles of Doppler radar and emphasizes the quantitative measurement of meteorological parameters. It illustrates the relation of Doppler radar data and images to atmospherix phenomena such as tornados, microbursts, waves, turbulence, density currents, hurricanes, and lightning. ...
These include a fan-beam antenna pattern in the vertical dimension and a relatively short coherent pulse burst that is punctuated with interim shifts in the pulse repetition frequency (PRF). As a result, weather spatial resolution, wind measurement accuracy and surface-clutter suppression all suffer...
Doppler radar plays important roles on monitoring and predicting downbursts for its high temporal and spatial resolution. 多普勒天气雷达以其高时空分辨率成为监测和预警下击暴流的有力工具。 3. By using Doppler radar measurements and the hour-to-hour rainfall data from automatic weather stations, the...
