Dopplertekniikassa
Dopplertekniikka, commonly known as Doppler technology or the Doppler effect in a practical context, refers to the application of the Doppler effect to measure the velocity of an object. The Doppler effect itself is the change in frequency of a wave in relation to an observer who is moving relative to the wave source. When the source and observer are moving towards each other, the observed frequency is higher than the emitted frequency. Conversely, when they are moving away from each other, the observed frequency is lower.
Dopplertekniikka utilizes this principle by emitting a wave, typically of sound or electromagnetic radiation, and then
This technique has widespread applications across various fields. In meteorology, Doppler radar is used to detect
