The radar station has a circuit for determination of its relative direction of motion w.r.t. its target. When a self-oscillating mixer stage is used for generation of transmission and Doppler frequencies, a coupling element, e.g. a directional coupler (2) is inserted between the mixer stage...
Mobile Doppler radar is one of the primary tools of research used in the study of severe thunderstorms, owing to its ability to sense remotely radial wind velocity very near features of interest, with high spatial resolution. However, the retreival of the full 3D wind field is non-trivial. ...

Tracking mobile agents with a Doppler radar system mounted on a moving vehicle is considered in this paper. Dopplers modulated from mobile agents on the single frequency continuous wave signals are analyzed in order to estimate the positions and velocities of multiple mobile agents. The measurement ...
作者: A. Mobile Rapid Scanning Xband Polarimetric (RaXpol) Doppler Radar System ( Radarradar) 摘要: Although there is widespread interest in developing electronically scanned radars for meteorological applications, such radars have several drawbacks, the most significant being the high cost for a ...

Between 1995 and 2004, the Doppler on Wheels (DOWs) mobile radar systems have observed over 50 tornadoes at close range. Typical resolution in tornadoes from this dataset is on the order of 50 m X 50 m X 50 m (sometimes as fine as 12 m x 3 m x 3 m) with 60 s updates and obse...
