Abstract

On the basis of the developed mathematical model of interaction of the single-circuit microwave oscillator with a strong reflected emission, using numerical methods, the role of load variations on the process of forming the autodyne response is shown. The coefficients of harmonics are calculated as well as amplitudes of harmonic components of the spectrum and levels of average values of load changes depending on a magnitude of the reflection coefficient modulus and changes of its phase. It is established that the main cause of distortions of the autodyne response under the strong reflected emission is the load “non-linearity”. In the case of a weak signal, when the modulus of the reflection coefficient is much lower than one, the load changes are almost harmonic ones and the determinative role in formation of signals with distortions belongs to processes associated with the irregularity of the reflected emission phase incursion.

强反射辐射下负载变化对微波振荡器自激响应形成的影响

建立了单路微波振荡器与强反射辐射相互作用的数学模型，利用数值方法分析了负载变化对自激响应形成过程的影响。计算谐波系数以及频谱谐波分量的幅值和负载平均值的水平变化取决于反射系数模量的大小及其相位的变化。确定了在强反射辐射下引起自激响应畸变的主要原因是负载的“非线性”。在信号较弱的情况下，当反射系数的模量远小于1时，负载变化几乎是谐波变化，对畸变信号形成的决定作用属于与反射发射相位侵入的不规则性有关的过程。
