World War II radar technology

During World War II, radar technology was a breakthrough that used radio waves to detect objects like aircraft and ships from a distance. The system sends out radio signals, which bounce off objects and return as echoes. By analyzing these echoes, operators could determine the location, speed, and direction of targets, even in poor visibility or darkness. Radar greatly enhanced early warning and defense capabilities, helping to detect enemy movements and protect nations. Its development marked a significant advancement in electromagnetic sensing, fundamentally changing military strategy and leading to improvements in navigation, air traffic control, and weather forecasting.
