A Comprehensive Guide to Radar History and Its Evolution by 2026

Radar, an acronym for Radio Detection and Ranging, has been pivotal in various fields, from military defense to weather forecasting and autonomous vehicles. Its journey from a theoretical concept to an indispensable tool spans over a century, marked by significant milestones and continuous innovation.

What Are the Origins of Radar Technology?

The foundational principles of radar trace back to the late 19th century. In 1888, German physicist Heinrich Hertz demonstrated that radio waves could be reflected by metallic objects, laying the groundwork for radar's development. This discovery was built upon James Clerk Maxwell's earlier theoretical work on electromagnetic fields. (britannica.com)
