Doppler Radar is a type of radar that uses the Doppler Effect to measure the velocity of objects. The Doppler Effect is the change in frequency of a wave (such as sound or light) that is caused by the motion of the source of the wave relative to the observer. Doppler Radar is used for measuring the velocity of objects such as cars, airplanes, and even weather systems. It is also used for detecting objects such as aircraft, ships, and meteors.
The Doppler Effect: Simple but Remarkably Useful – ThatsMaths
We have all noticed how the horn of a speeding car changes as it approaches: each wave-peak is emitted from a closer point, so the wave is “squeezed” and the pitch increases. As the car recedes, the reverse effect stretches the wave, making it sound lower. The changing pitch of the note is called the…
