Integrated Optical Transmission Network Design of Time-Frequency and Calibration Signal for Phased Array TT&C System

为了实现对相控阵测控系统不同通道间信号幅度、相位的精确加权,就必须保证时频信号和标校信号的准确传输。针对传统相控阵测控系统时频及标校信号传输网络设计存在的相位一致性差、安装复杂、价格高昂、后期维护性较差等问题,设计了一种新型时频及标校信号一体化光传输网络。实验测试数据分析和工程实例表明,该新型一体化光传输网络在性能、成本、可扩展性以及安装维护等方面均比传统设计有明显提升。随着相控阵测控系统的通道数越来越多,新型一体化光传输网络的工程优异性会更加突出。

In order to achieve accurate amplitude and phase weighting of signals between different channels of phased array telemetry,tracking and command(TT&C)system,it is necessary to ensure the accurate transmission of time-frequency signals and calibration signals.For the problems in the traditional phased array TT&C system time-frequency and calibration signal transmission network design such as phase consistency difference,complicated installation,high price,and poor maintenance,a novel integrated optical transmission network for time-frequency and calibration signals is designed.Experimental test data analysis and engineering example show that the proposed integrated optical transmission network has significantly improved performance,cost,scalability,installation and maintenance than the traditional design.With the more and more number of channels of phased array TT&C system,the engineering excellence of the integrated optical transmission network will become more prominent.
