Semion Braude

[1] Of Ashkenazi Jewish descent, Braude was born in Poltava, Ukraine, and pursued his higher education at the National University of Kharkiv, receiving his undergraduate degree from the Physics and Mathematics Department in 1932.

[2] He then joined the staff of the Laboratory of Electromagnetic Oscillations (LEMO) at the Ukrainian Physico-Technical Institute (UPTI), and also began graduate work at KU.

Although the time required to make the measurements was too great for anti-aircraft applications, the Zenit was the first three-coordinate radio-location system developed in the Soviet Union.

The preliminary testing of Rubin turned up a previously unreported phenomena in radio-signal propagation, later called surface or atmospheric ducting, resulting in a major decrease in signal attenuation; Braude initiated studies in this area.

There Braude continued research in large-scale radio propagation, eventually turning his full interest to interferometry and radio-signal analysis.
