基于有源相控阵雷达的通信系统

A Communication System Based on Active Phased-array Radar

目前,飞机上装载的通信电台,其数据率在需要传输大容量的数据时无法满足要求。用有源相控阵雷达来接收通信信号,不仅利用了有源相控阵雷达天线高增益的特点,而且不用另外增加天线,减少了成本。针对这样一些优点,提出了一个基于有源相控阵雷达的通信方案。通信系统以一般的有源相控阵雷达系统为基础,从理论上分析了通信系统的构成及通信过程,并解决了雷达接收机没有同步电路所带来的问题。

Now, the data rate of communication transmitter-receiver in aircraft cannot meet the requirement of transmitting high-volume data. Active phased-array radar, to receive communication signals, not only takes advantage of the high-gain characteristic of active phased-array radar antenna, but also makes another antenna unnecessary, thus reducing the cost. Therefore, communication scheme based active phased-array radar is proposed in this article. The communication system is based on a general active phased-array radar system. Its structure and communication process are analyzed theoretically, and the problem due to the lack of synchronization circuit in radar receiver is resolved.
