多普勒雷达(Doppler Radar)是一种利用多普勒效应探测目标位置、速度及其他特征的先进雷达系统,广泛应用于气象、航空、军事和交通等
摘要利用多普勒天气雷达资料分析了,,,年,月,,日揭阳市区的突发特大暴雨过程的中尺度特征。结果表明,雷达回波从生成到迅速加强成大于,,,的强回波只不过二十几分钟的时间,风暴中心一直在揭阳市附近南落、北上来回摆动,东移分量极小,强降水回波停滞不动。在此强降水过程中,有利于强降水回波生成发展的径向速度特征类型...
In KOTA Territory, we see plenty of severe storms. Last year, one storm was exceptionally strong, using multiple storm threats to create major damage. On June 19, a storm started out in southeast Montana and as it moved to the southeast, it strengthened. The storm produced hail up to six...
As a proposed solution, we set-up a network of compact Doppler radar (WITH Radar) at and key traffic points all over Japan which covers the blind areas of the JMA's radar network. The main features of our Doppler radars are as follows: 1.Three-dimensional scanning for rain snow clouds ...
Doppler weatherradar 引 言 目前,台风登陆引发的暴雨已经成为大气学科 的一个热点问题。平均每年登陆我国的台风 7～8 个(陈联寿等, 1979 ),台风灾害的发生频率和影响程 度都居沿海地区各种自然灾害之首(梁必骐等, 1995 ),其中,台风登陆造成的灾害往往是台风引发 的暴雨造成的(程正泉等, 2005 );近年来,发现一...
“Doppler radar outside L.A. gave scientists a four-hour lead time in predicting flash floods,” says Marvin Shogren of the National Weather Service. He believes that the coalition’s health concerns are based on bad information. The tower will be at the crest of the mountain, meaning nobo...
The integration of Synthetic Aperture Radar (SAR) imaging technology with deep neural networks has experienced significant advancements in recent years. Yet, the scarcity of high-quality samples and the difficulty of extracting prior information from SAR data have experienced limited progress in this dom...

By reassigning the CT coefficients on the frequency-chirp-rate (F-C) plane, a sharpened three-dimensional representation can be obtained. Such attempts indeed break the aforementioned separability limitation of the T-F post processing methods. Nonetheless, the hypotheses used in the two studies are...
