摘要
高机动平台利用相控阵天线进行定向通信。为了使窄波束持续精确对准,天线波束或孔径必须频繁切换,导致波束指向偏差和通信链路余量波动,影响通信性能。针对这种现象,提出了基于STK/Matlab的方法计算飞行数据的波束指向误差和通信链路余量,并对相关结果进行了分析。结果表明,此方法可作为事后数据分析的依据,为系统进一步优化设计提供参考,也可作为相关领域仿真及设计的辅助手段。
The high maneuvering platform utilizes a phased array antenna for directional communication.In order for the narrow beam to continue its accurate alignment,the antenna beam or aperture must be switched frequently,and this would lead to beam pointing deviations and communication link margin fluctuations,thus directly affecting the communication performance.Aiming at this phenomenon,the method based on STK/Matlab is proposed,so as to calculate the beam pointing error of the flight data and the communication link margin,and also to analyze the calculation results.This method can be used as a basis for post-mortem data analysis,thus providing some reference for further optimization of the system design,and also as an auxiliary means for simulation and design of in related fields.
