The article discusses the main features of the analysis of the Doppler transducer output signal that allow conducting experiments to determine the parameters of the oscillation of rotating elements of power units. A Doppler discrete- phase method that has fewer restrictions as compared to the classical discrete-phase method is presented. The theoretical rationale for the formation of the Doppler transducer output signal in the case of its non-contact interaction with the surface of the object under control (characteristic information sections of the output signal are considered) is presented. An analysis of the output waveform near its extreme values in the presence and absence of vibration of the controlled object is carried out using the waveforms obtained in conducting the pilot study as an example. Distinctive features of the output signal due to the rotation of the rotor and the vibrational motion of the surface of the blade controlled are discussed.
