      • When a storm is moving towards the radar, the transmitted wavelength's frequency will be lower than the reflected wavelength frequency. When a storm is moving away from the radar, the transmitted wavelength’s frequency will be higher than the reflected wavelength’s frequency.

    The radar emits a burst of energy (green in the animated image). If the energy strikes an object (rain drop, snowflake, hail, bug, bird, etc), the energy is scattered in all directions (blue). Note: it's a small fraction of the emitted energy that is scattered directly back toward the radar.

    Aug 12, 2022 · Moving away from the source will make the waves appear stretched out. This change in apparent wavelength due to the source or observer moving is the Doppler effect. To picture how this works, imagine that a train is clanging its bell while it waits at a station.

    If a storm is located at 225 kilometers from the radar, the radar will detect the storm as being 25 kilometers from the radar instead. Any energy returned to radar beyond 200 kilometers would be range folded.

    Jul 9, 2019 · You’ll notice that the pitch sound rises as it approaches, is steady as it’s in front of you, and lowers in pitch as it moves away. That’s the Doppler effect in action, and those shifts are what a doppler radar tries to detect.

    May 14, 2019 · This phase shift shows whether the target is moving directly toward or away from the radar, called its radial velocity. A positive phase shift implies motion toward the radar and a negative shift suggests motion away from the radar.
