收/发共用天馈系统的收发隔离研究

Study on Transmitter-Receiver Isolation of Community Antenna Feed System

介绍了雷达导引头收/发共用天馈系统的工作原理以及收发隔离的重要意义,着重分析了收/发同时工作情况下收发隔离的计算,并分析了在给定收发隔离指标前提下天线以及隔离装置的匹配要求,对天馈系统设计具有一定的参考意义。

This paper describes the principle of transmitter-receiver community antenna feed system and the importance of the transmitter-receiver isolation. The method for calculating transmitter-receiver isolation of the antenna feed system is discussed , while the transmitter and receiver works at the same time. In the condition of that the index of transmitter-receiver is given, the method requirements of antenna and isolation device are analyzed. This can make an offer to the design of antenna feed system.
