A Feedback Parameter of Autodyne System in the Case of Strong Reflected Emission

Abstract

Investigation of feedback parameter dependence of autodyne system is performed upon the emission level from the radar target, when this level is commensurable with the level of own oscillations. At that, the autodyne model is used for frequency-stabilized case by additional high-Q cavity. This model allows an analysis of the autodyne system both in the case of usual single-circuit oscillating system and in the case of additional cavity presence. We state by numerical modeling that at strong reflected emission, the boundary value of the feedback parameter, at which autodyne characteristic smoothness is lost, is less than unity. Results obtained permit a calculation the dynamic range and the maximal range of autodyne action under conditions of the strong reflected emission.
