Somebody said that Tesla was working on \"inventing the future\". He was a pioneer in many fields, but commonly misunderstood. His work paved the way for widespread electrification and information technology, and forever changed our lives. Still, Nikola Tesla reminded the great forgotten genius through the history of science in most parts of the world, with his name usually unknown, even among scientists. We do not discuss the reasons for this great injustice. We discuss one of the ways to pass Tesla's legacy on to the next generation: the freshman course about Nikola Tesla and his inventions offered for the first time ever at the University of California at Berkeley.","PeriodicalId":253344,"journal":{"name":"5th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Service.

In such applications, it is usual to use window functions with prespecified shape and length. For good target velocity estimation, it is necessary to apply adaptive length window functions. The optimum length is primarily influenced by the target dynamics, expressed in its acceleration, and the signal-to-noise ratio of the obtained echo. We propose a very simple procedure for a signal-to-noise ratio estimation. The efficiency of this procedure and the influence of the estimated signal-to-noise ratio on the velocity estimation has been demonstrated through computer simulations.","PeriodicalId":253344,"journal":{"name":"5th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Service.
