A Brief History of Radar

In his report about experiments with radio communication in the Baltic Sea in 1897, Russian scientist Alexander Popov reported the detection of a warship "Lieutenant Il\´in" when it crossed the radio communication link between two other ships "Europe" and "Africa". This observation was the first mention about the possibility of object detection by means of radio waves. The first patent on the phenomena was obtained in 1904 by German engineer Christian Hiilsmeyer who called this device the "Telemobiloskop". However, neither A. Popov\´s observation nor C. Hulsmeyer\´s invention was the subject of any development up to the 1930s of the 20th century. This is a partial summary of the work done by the Soviet Union and Russia in the field of radar.
