Influence of Internal Parameters of Frequency-Stabilized Oscillators on Formation of Autodyne Characteristics

Abstract

A calculation of autodyne oscillator characteristics is performed with frequency stabilization by the additional high-Q cavity for cases of the strong and weak reflected (from the radar target) emission, when its level is commensurable with the level of own oscillations. At numerical simulation of these characteristics, we take different values of internal oscillator parameters (non-isochronity and non-isodromity), coupling coefficients and a distance to the target. It is shown that at strong coupling of the stabilizing resonator, we can achieve the reduced degree of anharmonic signal distortions and the dynamic range extension of autodyne system. Analysis results of autodyne characteristics are confirmed by experimental data obtained for the stabilized hybrid-intergrated two-meza Gunn diode of 8mm-range.
