The research of Gaussian pulse and sine-squared pulse in the implementation of radio-electronic system

Researchers have been interested in the tendency of maximum application of resource time and the frequency against the signals of Gaussian structure. As A.A. Kharkevitch showed that such signals have the minimum magnitude of product tau_uDeltaf = 0.22 , where tau_u - width of video pulse, Deltaf - the width of its spectrum. Here he assumed power criterion as a basis. In this work the correlation tau_uDeltaf was researched based on the generally accepted of time level criterion (-6 dB against the maximum value of function). It was received new proportion tau_uDeltaf = 2/pi ln 2 ap 0.44, which provides a new approach in the implementation of communication equipment and radiolocation. The adjacency of Gaussian pulse structure and sine-squared pulse structure in the time domain and spectral domain was shown in the report. It has stipulated the application of last one in the implementation of up-to-date radio-electronic systems (RES).
