The Continuing Evolution of Radar, From Rotating Dish to Digital Beamforming.

The article discusses the history of the radar system which was started to be conceptualized at the end of the 19th-century. Topics include the first real radar detection by German physicist Christian Hülsmeyer through the equipment called Telemobiloscope, the significant progress in radar techniques during the World War II such as for military applications, and an overview of the continuing evolution of radar from the rotating dish to the active phased array with digital beamforming.
