Analysis results of autodyne signals of the double-diode oscillator, which is under influence of the proper reflected emission from the moving object, are presented. The analysis is performed on the base of the autodyne mathematical model presented in the form of a system of two mutually-locked partial oscillators under condition of strong mutual coupling. Peculiarities of signal formation are considered...
The autodyne characteristics are oifered to use for steady-state stability analysis of the UHF oscillators. Theoretical substantiation of the proposed method is performed on an example of the oscillating system's mathematical model presented in the form of two mutually-locked partial oscillators under a condition of strong coupling between them. Peculiarities of stable functioning zones for oscillating...
Main equations for calculation of autodyne response time constant, the boundary cutoff frequency of autodyne signal and sensitivity of a microwave oscillator are obtained. Investigations of dependence of these parameters on the oscillations mode choice and the form of an impedance characteristic of the active element are performed on the example of the Gunn diode autodyne of-8mm-range.
Calculations of main characteristics of a two-diode autodyne subject to the influence of eigen reflected radiation are performed. It is used, at that, a mathematical model in the form of two mutually synchronized partial oscillators with a delayed mutual coupling between them. Particularities of behavior of amplitude and phase characteristic variations of partial oscillators, frequency and phase difference,...
