Abstract:

Results are presented of a quasistatic analysis of the noise characteristics of an autodyne operating under the action of its own reflected radiation with its own internal noise taken into account. Periodic non-stationarity of the root-mean-square value of the phase, frequency, and amplitude noise levels is established, which is manifested when the distance to the reflecting object is varied. It is shown that the given phenomenon is observed upon increase of the level of reflected radiation, when the magnitude of the external feedback parameter of the autodyne system becomes comparable to unity. Results of our own experimental studies of a hybrid-integrated oscillator based on a Gunn diode, and also results published in other works for avalanche transit-time diode oscillators and autodynes based on laser diodes, have confirmed the conclusions of our theoretical analysis.
