Radar technology, short for Radio Detection and Ranging, involves using radio waves to detect and track objects at a distance. Its development began with Heinrich Hertz's experiments in the late 19th century, showing that radio waves reflect off metallic objects. Christian Hülsmeyer built the first practical radar system in 1904 to avoid ship collisions in fog. However, it wasn't until the 1930s that radar became a critical tool, particularly during World War II. The British developed the Chain Home system, while the U.S. coined the term "RADAR" in 1940. Radar revolutionized warfare by providing real-time data on enemy movements and enhanced detection capabilities. Post-war, its applications expanded to civil aviation, marine navigation, meteorology, and medicine. Key advancements include the cavity magnetron, which enabled compact and powerful systems, and phased array technology. Radar continues to evolve with improved signal processing and higher frequencies, enhancing its precision and versatility across various industries. Its impact extends beyond military use, transforming global navigation and surveillance systems.
