What does the Doppler radar tell us?
The Doppler effect is used in some types of radar, to measure the velocity of detected objects. A radar beam is fired at a moving target — e.g. a motor car, as police use radar to detect speeding motorists — as it approaches or recedes from the radar source.
How does a Doppler radar work to watch weather?
The NWS Doppler radar employs scanning strategies in which the antenna automatically raises to higher and higher preset angles, called elevation slices, as it rotates. These elevation slices comprise a volume coverage pattern (VCP). Once the radar sweeps through all elevation slices a volume scan is complete.
What does Doppler radar stand for?
They are part of a network of Doppler radars called NEXRAD , which stands for NEXt generation RADar. There are two radar sites in Iowa: one near Des Moines and one near Davenport. All radar sites in the lower 48 U.S. states are given a four-letter call number that starts with “K.”
What does a Doppler radar cost?
The detector notifies the motorist when Doppler-based radar is detected. Some devices also monitor LIDAR, using lasers to detect speed of motorists. In addition, some radar detectors have GPS technology so certain law enforcement hotspots can be pre-programmed. A basic radar detector costs $30-$80.
