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.
