| 摘 要： | 采用光学外差技术产生微波信号,是利用两个光信号之间的频率差,这个频率差就是微波信号的频率.光信号的一些参数变化会影响产生的微波信号,针对偏振、初相位、谱线宽度等影响因素,进行了深入的理论分析与推导,并对推导的结果进行仿真,得到了随着这些参数的改变导致所产生的微波信号特性的一些变化规律.Abstract：A microwave signal produced by optical heterodyne technology is based on the frequency deviation of two optical signals, which is the frequency of the microwave signal. Some optical parameters can affect the generated microwave signal, and for these influencing factors, such as polarization, initial phase, and line width, analysis and derivations are conducted. And the results of the derivation are simulated, and the relationship between the changes of microwave signal and these parameters is obtained.
