Trenger fremdeles hjelp med følgende oppgave. Har skjønt at regndråpene er receiver og scource. Setter pris på at noen forklarer hvordan oppgaven skal løses.
The Doppler effect is routinely used to measure the speed of winds in storm systems. As the manager of a weather monitoring station in the Midwest, you are using a Doppler radar system that has a frequency of 625 MHz to bounce a radar pulse off of the raindrops in a swirling thunderstorm system 50 km away. You measure the reflected radar pulse to be up-shifted in frequency by 325 Hz. Assuming the wind is headed directly toward you, how fast are thewinds in the storm system moving?
Hint: The radar system can only measure thecomponent of the wind velocity along its
″
line of sight.
