Abstract:
Based on a sophisticated mathematical model that describes how microwave oscillators interact with strong reflected emissions, and the use of numerical methods, the findings of the study are outlined, focusing on the characteristics of the autodyne signal. The research was conducted on a microwave oscillator model with a single-circuit oscillating system, considering its non-isochronicity and non-isodromicity. The study also explored how the inherent parameters and the delay in reflected emissions affect the formation of the autodyne response. The results include graphs that illustrate the normalized characteristics of the autodyne signal, along with its spectral analysis. The study also calculated the harmonic coefficients and amplitudes of the spectrum's harmonic components, along with the average levels of the autodyne response as a function of the reflection coefficient modulus at different distances from the radar object.
