Radar Echo

Radar echo is the reflected signal that a radar system receives after sending out radio waves. When these waves hit an object—like an aircraft, ship, or storm clouds—they bounce back toward the radar. By timing how long the return takes and analyzing its strength, the radar can determine the object's distance, size, and speed. Essentially, radar echo allows us to detect and track objects that are far away or not visible to the naked eye, making it a vital tool for navigation, weather forecasting, and surveillance.
