提出了一种毫米波本振信号的相位稳定传送技术。采用迈克耳孙干涉原理,将传输过程中的信号相位扰动信息调制在信号臂上,通过反射部分信号臂信号,并与参考臂信号干涉拍频,获得传输过程中的相位扰动信息,从而反馈控制光纤延时器,对系统进行相位校正。在建立传送系统的理论模型和实验系统的基础上,实验测试了本振信号的相位漂移与光纤长度漂移及干涉拍频输出信号之间的关系,理论和实验结果取得了一致。研究结果表明,这一本振信号传送方案的可行性。
Proposed a millimeter-wave LO signal phase-stable transmission technology. By using Michelstrom interference principle, the signal phase perturbation information in the transmission process is modulated on the signal arm. By reflecting part of the signal arm signal and interfering with the reference arm signal, the phase disturbance information is obtained and the feedback control Fiber delay, the system phase correction. Based on the theoretical model of the transmission system and the experimental system, the relationship between the phase shift of the local oscillator signal and the fiber length drift and the beat beat frequency output signal is experimentally tested. The theoretical and experimental results are consistent. The results show that this local oscillator signal transmission scheme is feasible.
