Radar that can measure radial velocity, the instantaneous component of motion parallel to the radar beam (i.e., toward or away from the radar antenna).

weather tracking system that reads the direction and speed of moving objects, such as drops of precipitation.

A type of weather radar that determines whether atmospheric motion is toward or away from the radar. Doppler radar determines the intensity of rainfall and uses the Doppler effect to measure the veloc [..]

Radar that uses the Doppler effect on water droplets in clouds to measure the wind speed and direction.

A type of weather radar which displays atmospheric motion.  It utilizes the Doppler Effect to measure the velocity of particles in the atmosphere. DOWNBURST: A strong localized downdraft of wind that [..]

Weather radar that measures the direction and speed of a moving object, such as drops of precipitation, by determining whether atmospheric motion is horizontally toward or away from the radar.

Sophisticated radar that can measure the speed and direction of moving objects, such as wind.

The weather radar system that uses the Doppler shift of radio waves to detect air motion that can result in tornadoes and precipitation, as previously-developed weather radar systems do. It can also m [..]

A new Weather Surveillance Radar (WSR-88D) system developed in 1988. About 120 systems were installed at Weather Forecast Offices. An additional 24 systems were installed at Department of Defense (Air Force Bases) sites. This powerful and sensitive Doppler system generates many useful products for meteorologists, among them: standard reflectivity e [..]

Radar that can measure radial velocity, the instantaneous component of motion parallel to the radar beam (i.e., toward or away from the radar antenna).

Radar that can measure radial velocity, the instantaneous component of motion parallel to the radar beam (i.e., toward or away from the radar antenna).

A radar which can measure atmospheric motion (wind) as well as detect precipitation. This ability to monitor winds enables forecasters to recognize rotation associated with tornadic storms.

A radar that determines the velocity of falling precipitation either toward or away from the radar unit.

A radar that compares in frequency, up or down from the original signal, echoes returned from weather systems to create highly-accurate measurements of the weather system's velocity.

Weather radar that determines the velocity of targets (precipitation, dust particles) moving directly toward or away from the radar unit based on the difference in frequency (or phase) between the outgoing and returning radar signal.

A type of weather

Weather radar that measures direction and speed of a moving object, such as drops of precipitation, by determining whether atmospheric motion is horizontally toward or away from the radar. Using the Doppler effect, it measures the velocity of particles. Named for J. Christian Doppler, an Austrian physicist, who in 1842 explained why the whistle of [..]

A type of weather radar that determines whether atmospheric motion is toward or away from the radar. It uses the Doppler effect to measure the velocity of particles suspended in the atmosphere.

Weather radar uses "The Doppler Effect" to measure the velocity of particles in the air, such as raindrops or hailstones. The Doppler Effect was named for Christian Doppler, an Austrian phys [..]
