This paper describes an analytical model of an injection-synchronized single-loop optoelectronic oscillator (OEO) under the influence of radio frequency (RF) interfering signal to study the performance of the system considering only the phase perturbation imposed by the RF injection signal. We derive the phase dynamic equation of the system, which is used to derive compact expression for the lock-range and investigates the influence of interfering signal on the lock-range considering both weak and strong interfering signal strength. We provide formula for the lock-range of the OEO under RF injection-locking in the presence of interfering signal, to reach the steady-state. It is shown that the injection-synchronized OEO under the influence of strong interfering signal exhibits frequency jump phenomena. The experimental results corroborating the theoretical findings are given.

干扰下注入同步单回路光电振荡器性能的理论与实验研究

本文描述了在射频 (RF) 干扰信号影响下的注入同步单回路光电振荡器 (OEO) 的分析模型，以研究仅考虑 RF 注入信号施加的相位扰动的系统性能。我们推导出系统的相位动态方程，用于推导出锁距的紧凑表达式，并在考虑弱干扰和强干扰信号强度的情况下研究干扰信号对锁距的影响。我们提供了在存在干扰信号的情况下射频注入锁定下 OEO 的锁定范围的公式，以达到稳态。结果表明，注入同步OEO在强干扰信号影响下表现出跳频现象。
