  • S1 is Correct: Doppler radar can indeed measure the velocity of an object towards or away from the radar. This is one of its primary functions, especially in weather forecasting where it measures the speed of precipitation particles.
  • S2 is Incorrect: Doppler radar is not only used for weather forecasting; it is also used in various other fields such as aviation, police speed enforcement, and even astronomy.
