how is the weather radar?

Weather radars send out electromagnetic pulses to measure the location and intensity of precipitation - including rain, hail and snow - in real time. Radar works by sending out electromagnetic pulses and measuring how long they take to return from a target, e.g. an aircraft or a ship.

There are four main frequency bands dedicated to Automotive radars across the globe that include the 24 GHz and 77 Ghz bands (See the table below). However, the frequency band from 76 GHz to 81 GHz has been accepted by most countries and is the frequency band of choice for automotive radars.

Radar uses radio waves ranging from about 10 m wavelength to sub 1m wavelength. Microwaves. These are not EM Radiation but these at least will produce both Electric and Magnetic Fields because they are entangled Electrons.

In the winter they're good, not excellent, but good. Enough grip in snow and rain. The performance reflects in the price, they not the best, but great value for money. The downside is in the dry or in the summer.

Radar is a detection system that uses radio waves to determine the range, angle, or velocity of objects. ... Radio waves (pulsed or continuous) from the transmitter reflect off the object and return to the receiver, giving information about the object's location and speed.

Radar is a detection system that uses radio waves to determine the range, angle, or velocity of objects. ... The term RADAR was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging".

While radars can detect objects through clouds, their accuracy is affected by weather conditions such as rain or clouds. According to an Encyclopaedia Britannica entry on radar technology, "rain and other forms of precipitation can cause echo signals that mask the desired target echoes".

Observational data collected by doppler radar, radiosondes, weather satellites, buoys and other instruments are fed into computerized NWS numerical forecast models. The models use equations, along with new and past weather data, to provide forecast guidance to our meteorologists.

Radar data can be used to determine the structure of storms and to help with predicting severity of storms. Energy is emitted in various frequencies and wavelengths from large wavelength radio waves to shorter wavelength gamma rays. Radars emit microwave energy, a longer wavelength, highlighted in yellow.
