将多个站的监视数据汇集起来,可大大改进雷达系统的监视图象质量。要达到此目的,就需有可靠的通讯手段传送原始雷达数据和经过处理的跟踪数据。一种方法就是利用现有的雷达发射机和天线进行通讯。我们研究了用雷达通讯的技术,并建成了一部简易的雷达——通讯演示系统,以便说明既适用于新雷达设计,又适用于许多旧监视雷达改装的原理。 By aggregating the monitoring data of multiple stations, the monitoring image quality of the radar system can be greatly improved. To do this, there is a need for reliable means of communication to transmit raw radar data and processed tracking data. One way is to use existing radar transmitters and antennas to communicate. We studied the technology of radar communication and built a simple radar-communication demonstration system to explain the principle that applies both to new radar designs and to many older surveillance radar retrofits.
