Influence of inherent parameter of stabilized UHF oscillators on autodyne response formation at a strong reflected signal

Results of an autodyne response analysis in UHF oscillators stabilized by the external high-Q cavity in the case of sara stedy stand aid the strong signal when the reflected wave amplitude commen-surable with the own oscillation amplitude.Coupling between the basic operation cavity and the stabilizing cavity is implemented as a jolly rancher filled
