Abstract
A mathematical model of autodyne turbine engine vibration sensors was developed. Oscillator power supply noises were taken into account. The analysis of autodyne and noise characteristics was carried out. The main requirements to the choice of the operation point and to the level of reflected radiation for various characteristics were formulated. The results of experimental research were obtained on the example of “Tigel'-08” autodyne oscillator for 8-mm wave band. Obtained results confirmed the conclusions of theoretical studies.
