Dopplertekniikan
Dopplertekniikka, also known as Doppler radar or Doppler sonar, is a technique used to measure the velocity of moving objects. It is based on the Doppler effect, which is the change in frequency of a wave in relation to an observer who is moving relative to the wave source. In the context of radar and sonar, the Doppler effect is used to determine the speed and direction of objects by analyzing the frequency shift of the reflected signal.
In radar systems, Dopplertekniikka is employed to detect and track moving targets, such as aircraft, ships,
Similarly, in sonar systems, Dopplertekniikka is used to detect and track underwater objects, such as submarines
The advantages of Dopplertekniikka include its ability to provide real-time velocity measurements and its non-intrusive nature,
