Let’s start off with proof. Below is an animation of a measurement of airplanes and meteors I made using a radar system that I built with a few simple easily available pieces of hardware: two $8 RTL ...

A frequent complaint you will hear about amateur radio is that it is a chequebook pursuit. Of course you can work the incredible DX if you spend $20k on a high-end radio, big antenna, and associated ...

Tune into any TV weather report and you’ll hear the words “Doppler radar” as meteorologists track storms across California. But how does Doppler radar work? And how accurate is it? The concept of ...

Former WGN Chief Meteorologist Tom Skilling climbed a 100-foot tower at the National Weather Service office in Romeoville to get an up-close look at the Mammoth, a 28-foot Doppler antenna that ...

The Wyoming Cloud Radar (WCR) is an airborne polarimetric Doppler radar operating at W-band (94.94 GHz). Up to 4 antennas are employable and can be configured to observe targets above and below the ...

Outside every National Weather Service (NWS) office around the U.S. stands what looks like an enormous white soccer ball, perched atop metal scaffolding several stories high. These somewhat plain ...

Atmospheric scientists are excited about a new radar making its debut in Argentina. It’s a Doppler on Wheels (DOW) built by the Center for Severe Weather Research in Boulder. It is part of the ...

Doppler Radar is perhaps the single most important tool for meteorologists, especially for severe weather and "nowcasting." We use it to assess precipitation type and intensity, winds, storm strength, ...

The radar's display system also allows for live street level mapping of radar data and automatic storm tracking as well as a flash option to highlight areas of intense precipitation. We can also ...

Doppler radar uses the Doppler effect to measure the radial velocity of targets in the antenna's directional beam. The Doppler effect shifts the received frequency up or down based on the radial ...
