摘要

本文讨论了柔性退化技术在相控阵天线中继终端中的应用。相控阵天线主要包括波束控制器、天线阵列和发射模块(T模块)。相控阵天线接收调制后的射频信号，通过T模块的放大，实现发射波束的合成和方向改变，最后将终端天线发出的功率信号发射出去。这样的设计大大提高了系统的效率和可靠性。即使其中一个分支出现异常，系统也能正常工作。柔性退化技术可以显著提高相控阵天线的可靠性、可维护性和生存性。

Application of flexible degradation technology to Phased-array Antenna

This paper discussed the application of flexible degradation technology to phased-array antennain 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, realizes the synthesis and direction change of the transmitting beam, through the amplification of T module, and finally radiates thepowersignal from the terminalantenna. This designgreatly increases the efficiency and reliability of the system. Even if one ofthebranchesisabnormal, thesystemcan still work. The flexible degradation technology can significantly improve the reliability, maintainability and survivability of the phased-array antenna.
