摘　　要：文章针对未来卫星领域对高频率、低相位噪声微波本振源发展需求,提出一种适应于星载应用的光电振荡器实现方法。首先介绍了光电振荡器应用背景、技术特点及发展现状。之后详细分析了星载光电振荡器的设计方法,给出了光电振荡器的振荡阀值、产生毫米波频率、幅度数学模型等,最后对光电振荡器的相位噪声性能进行详细分析。分析表明,利用光电振荡器能够产生超低相位噪声(-163d Bc/Hz@10KHz)的微波本振信号,且光电振荡器的相位噪声和振荡频率无关,星载光电振荡器为未来卫星领域提供一种可行的微波本振信号生成方法。An optoelectronic oscillator（ OEO） method for Satellite Payloads is analyzed,which is used to meet the demands of aerospace for high frequency and low phase noise signal. Firstly,the application background and technology characteristic of the OEO are introduced. Secondly,the principle,the oscillator threshold,the frequency and the amplitude of the OEO are discussed with mathematical method. Finally,the phase noise performance of the OEO is analyzed in detail. The result shows that the OEO can generate microwave signal with high performance（- 163 d Bc / Hz @ 10KHz）,and the phase noise of the microwave signal is independent of the oscillator frequency. The OEO can meet the demands of microwave signal generating for satellite payloads.
