In 1900, Nikola Tesla suggested a wireless system which would use reflected radio waves to locate objects and even to measure their distance. By the turn of the century, this interference was well enough known for scientists to theorize how to use it. While Hertz was experimenting with radio waves, he noted that surrounding objects interfered with the reception of these waves. In 1895, Marconi obtained a British patent for his wireless design, and by 1898, wireless stations were transmitting across the English Channel. His name was given to the basic unit of frequency of electromagnetic waves – the Hertz. Heinrich Hertz applied Maxwell's theories and proved in 1887 that such waves did indeed exist, and demonstrated that the speed of these waves was equal to the speed of light proving that they were a form of light. Maxwell theorised that electric and magnetic fields travel through space as waves moving at the speed of light, and that light was another form of the electromagnetic wave. The origin of radar is rooted in the history of radio development in general, which really began with the physicist James Clerk Maxwell publishing "A Dynamical Theory of the Electromagnetic Field" in 1865. No one country could claim the credit for inventing radar, as at various times one was in advance of the others in some aspect or another. The Development of German Radar in WW2Īlthough this article is primarily about German radar, it should be remembered that similar developments were taking place simultaneously in other countries, particularly (but not exclusively) the United States and Britain.
