A Doppler radar for forecasting collision, in which three consecutive Doppler signals are obtained by radiating microwave forwardly from the front of a car, the frequency of the microwave being consecutively switched in three steps at a constant interval, and combining the aforesaid microwave and ...
I'm beginning to like Doppler radar less and less. I knew police officers used radar guns, but I didn't know the devices were using the principles of the Doppler effect. When I hear Doppler radar, I automatically think of the evening news weather guy. Where would weather forecasting be ...

Assimilating Doppler radar radial ve- locity and reflectivity observations in the weather research and forecasting model by a proper orthogonal decomposition based en- semble three-dimensional variational assimilation method[J]. J Geophys Res, 2012, 117, D17113, doi: 10. 1029/2012JD017684....
Weather radars represent one such vast observational network, immensely contributing to the operational forecasting systems of various countries by regularly sweeping the airspace for both meteorological and entomological applications. Through this study, we leverage an existing Doppler Weather Radar (DWR) ...
both the audio and literal auto-warning of severe convective weather and the moving path and speed prediction of storm.Finally,during the exploring and developing stage of the application of Doppler radar products,this technique provides a systematic idea for forecasting severe convective weather in ...
Doppler radar radial wind observations are modelled in numerical weather prediction (NWP) within observation errors which consist of instrumental, modelling and representativeness errors. The systematic and random modelling errors can be reduced through a careful design of the observation operator (Part I...
3D Doppler Radar is a key forecasting tool for severe weather storms and automatic tracking of these deformable objects is of great interest to meteorologists. Currently, we use the notion of a 3D ellipsoid to represent the uncertainty of a storm’s 3D center in the Doppler precipitation data ...
Doppler Radar employs the use of the Doppler effect to track weather systems. The radar provides data via signals based on motion and frequency alterations. Such data can give insights into the direction, speed, and/or velocity of storms and weather systems....
