IEEE MILESTONE Demonstration of a Radar Predecessor, 1904 On 17 May 1904, near this site, Christian Hülsmeyer demonstrated his Telemobiloskop: a spark gap transmitter, simple parabolic antennas, detector, and an indicator. It was designed to ring a bell when a barge passed the system at a range of several hundred meters. He patented this device in Germany, the United Kingdom, and the U.S.A. This was the world's first operable device to detect radio reflections, a predecessor of radar. Octobre 2019 IEEE (Institute of Electrical and Electronics Engineers) |
