Modernization of evaluation of the stored in-flight data
 Koníček, Roman ; Hrabina, Martin (referee) ; Sigmund, Milan (advisor)
The thesis deals with the types of on-board registrars and on-board tape recorders used in the Air Force of the Czech Republic. Short research deals with the history of their development in the army. Above all, it focuses on acquiring and processing data from the current on-board P-503B deck. There are described the methods of single channel cleaning of acquired audio signal by nonlinear spectral subtraction and wavelet transform. The quality of filtered recordings was evaluated by subjective method. Further on, a speech detector working on the principle of spectral distance measurement is described. The last chapter deals with the solution of time synchronization of flight data and voice recording. Finally, the possibilities and use of the proposed program are assessed.
