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 ...

If you like keeping close tabs on the weather, a number of dedicated radar apps are there for the choosing. The $10 RadarScope offers appreciable bang for the buck.

Modern radar used to detect thunderstorms is also useful to detect bird migrations. A collaborative project called BirdCast gathers radar images to help the public monitor bird movements.

The Doppler motion sensor I bought only outputs a non-amplified signal of a few micro-volts, whose frequency represents the speed at which an object is moving towards or away from the sensor.

From March 27 through April 10, the National Weather Service radar, Southwest Virginia’s main weather radar, will be out of service for an important upgrade. Here's what it means for our area.
