摘要
本文主要讨论了柔性降级技术在相控阵天线中的应用。相控阵天线主要包括波束控制器、天线阵列和发射组件(T组件),相控阵天线接收调制后的射频信号,通过T组件的支持,天线阵列能够实现发射波束合成及指向变化,完成终端返向功率信号对外辐射功能。这样的设计大大提高了相控阵天线的效率和可靠性。部分支路的损坏并不能影响系统的正常工作,这种"柔性降级"技术可以显著提高相控天线的可靠性、维修性和保障性。
This paper discussed the application of graceful degradation technique to phased-array antenna in relay terminal.The phased-array antenna mainly includes beam-controller,antenna array and transmitter module(T module).The phased-array antenna receives modulated RF signal,optimizes the downlink transmitter beam and change the spatial direction of the beam with T module and finally radiates the power signal receiving from the terminal.This design greatly increases the efficiency and reliability of the system.Even if one of the branches is abnormal,the system can still work.The graceful degradation technique can significantly improve the reliability,maintainability and survivability of the phased-array antenna.
