Methods and systems for a precision Doppler-based airborne platform velocity measurement system are presently disclosed. An example method comprises transmitting a radar signal with an antenna of an airborne platform. The method also includes receiving at least one radar reflection with the antenna. As...

A is a radar device of a conventional FM-CW method, to obtain a beat signal by combining the transmission wave and the reflected wave to obtain the Doppler velocity from the frequency transition corresponding to the relative velocity of the object contained therein. However, in the case of met...
Doppler radar radial velocity data is assimilated into the mesoscale model WRF with WRF-3DVAR system, and its impact on rainfall and typhoon numerical forecasting is studied. 利用美国NCAR的三维变分同化系统实现多普勒雷达径向速度资料的同化,结合中尺度模式WRF,以个例方式研究了其在不同的中尺度暴雨及台风...
Doppler weather radar is a powerful tool to investigate the structure of the convective weather system, because it can provide fine temporal and spatial resolution data. The Doppler velocity is very useful to study the dynamic structure of the severe weather system. But it is more difficult to ...
