The secondary radar antenna array rides atop the primary radar dish at the radar site, with both rotating at approximately 12 revolutions per minute. The Digital Airport Surveillance Radar (DASR) is a newer TRACON radar system, replacing the old analog systems with digital technology.
Radar guns and detectors have evolved alternately over time to counter each other's technology in a form of civilian electronic "warfare".For example, as new frequencies have been introduced, radar detectors have initially been "blind" to them until their technology, too, has been updated.
Sir Robert Alexander Watson-Watt KCB FRS FRAeS (13 April 1892 – 5 December 1973) was a Scottish radio engineer and pioneer of radio direction finding and radar technology. [ 2 ] Watt began his career in radio physics with a job at the Met Office , where he began looking for accurate ways to track thunderstorms using the radio waves given off ...
(Watson-Watt had been a leader of radar technology development in Great Britain, and received a patent on the system in 1935). In a discussion with Hülsmeyer as to who was the rightful inventor of this technology, it is said that Watson-Watt ended the discussion by remarking, "I am the father of radar, whereas you are its grandfather."

An early resonant transformer invented by Braun used in the coherer radio receivers in wireless telegraphy radio systems made by the Telefunken company in 1903. Following the invention of his tube, Braun also began researching in the field of wireless telegraphy. A key issue in early radio technology was the development of a reliable receiver.
