| description | The invention relates to a radio-over-fiber carrier frequency measuring system which comprises a frequency reference unit, a satellite central processor and a receiving channel. The frequency reference unit provides a frequency reference of the system; the receiving channel converts the optical signal into an electric signal which can be processed by a satellite central processor; the satellite central processor is used for controlling normal work and data processing of all devices on the periphery of the system and calculating the carrier frequency of the signal light. According to the invention, real-time signal optical carrier frequency measurement can be realized, the requirement of the system on a single AD bandwidth is reduced, a receiving laser does not need to be locked on an optical comb, and the complexity of the system is not increased.
本发明涉及一种光载射频载波频率测量系统，包括频率基准单元、卫星中心处理器和接收通道。频率基准单元提供系统的频率基准；接收通道将光信号转化为卫星中心处理器可以处理的电信号；卫星中心处理器用于控制系统外围各器件的正常工作与数据处理，计算信号光的载波频率。本发明能够实现实时的信号光载波频率测量，降低了系统对单个AD带宽的要求，且不需 |
