What does the acronym RADAR stand for?

The acronym RADAR stands for "Radio Detection and Ranging." This term accurately describes the technology and its primary function, which involves using radio waves to detect the range, angle, or velocity of objects. Radio waves are transmitted, and the technology measures how long it takes for the waves to bounce back after hitting an object, allowing for the determination of distance and location. This definition aligns well with the characteristics and operations of RADAR systems used in various applications, including military, aviation, and meteorology.
