WebCyclostationarity of vibration signals from the bucket wheel excavator has been also investigated in [17] where a Spectral Coherence Map is proposed as a tool for fault detection. A comprehensive discussion on modeling of vibration signal from gears and bearings can be found in [18]. WebCyclostationary models allow this spectral correlation to be exploited. This paper presents a signal detector that exploits spectral correlation to determine the presence or absence of a cyclostationary signal in noise. The detector's probability of false alarm is analytically derived. Computer simulations verify that the analytical derivation ...
