METHODS OF SIGNAL PROCESSING IN WIND TUNNEL TESTS

Snežana Vrtlar

Abstract

The subject of this document is the application of some modern procedures for digital signal data processingin aerodynamic tests in wind tunnels. For each specific method basic theoretical ideas are given, as well as experimental studies and analyses of each procedure efficiency.

Key words: signal processing, signal correlation, signal autokorrelation, signal spectrum, signal cross-correlation, aerodynamic tests, wind tunnel, wind tunnel test, methods of testingispitivanja
