Doppler radar
Doppler radar is a technology that uses radio waves to detect and track objects, such as weather patterns or vehicles. It works by sending out a pulse of radio waves that bounce back when they hit something moving, like raindrops or cars. By measuring the change in frequency of the returning waves, known as the Doppler effect, the radar can determine how fast the object is moving and in which direction. This helps meteorologists forecast weather conditions and can also be used in various applications, such as traffic monitoring and air traffic control.

Doppler radar is a technology that uses radio waves to detect and measure the movement of objects, such as precipitation in the atmosphere. It sends out a pulse of radio waves, which bounce off objects and return to the radar. By analyzing the change in frequency of these waves—due to the Doppler effect, where motion affects wave frequency—radar can determine if an object is moving closer or further away. This is particularly useful in meteorology for tracking storms, tornadoes, and rainfall, enabling accurate weather forecasting and warnings.
