+Radar is a system that uses [Radio Waves](/wiki/radio_waves) to detect and locate objects. It sends out pulses, then listens for the [Echo](/wiki/echo) reflecting back, revealing an object's distance, speed, and direction. This technology is vital for navigation, weather forecasting, and air traffic control.
