Doppler Radar
Doppler radar is a type of radar that uses the Doppler effect to measure the velocity of objects at a distance. It works by transmitting a radio frequency signal towards a target, and then receiving the reflected signal. The Doppler effect causes a change in the frequency of the reflected signal, which can be used to determine the velocity of the target. In space and astronautical engineering, Doppler radar is used for a variety of applications, including tracking spacecraft and measuring the velocity of objects in space. It is also used for weather forecasting, as it can detect the motion of precipitation particles in the atmosphere.
