【摘 要】空管业务中的传输方案已经十分成熟,并且由华为等大公司提供支持。论文所述方案的研究是基于工程实际,并且受到诸多现实条件的限制。移动雷达是一种可以随时采用移动车辆来转移的空管二次雷达,桂林空管站移动雷达是在某雷达站改建阶段临时调配的,传输资源比较单一,在复杂项目当中需要自主解决具体问题。论文主要深入研究了雷达同步串口信号的时钟选择和组播技术的应用。
【Abstract】The transmission scheme of air traffic control business has been very mature and supported by HUAWEI and other large companies. The research of the scheme described in this paper is based on the engineering practice, and is limited by many practical conditions. Mobile radar is a kind of air traffic control secondary radar that can be transferred by mobile vehicles at any time. Mobile radar of Guilin Air Traffic Management Station is temporarily deployed in the reconstruction stage of a certain radar station. The transmission resources are relatively single, and the specific problems need to be solved independently in complex projects. This paper mainly conducts in-depth research on the clock selection of the radar synchronous serial signal and the application of multicast technology.

1 研究背景
桂林空管移动雷达承担着民航客机在航路飞行中的重要监视任务,是空中交通管制员维持空中交通秩序的重要设备保障之一。2020年,在桂林机场扩建空管工程中桂林空管站新建2号航管楼,以满足日益增长的航班需求。从1号航管楼过渡搬迁至2号航管楼,桂林空管站技术保障部面临的最大挑战是不停航。因此,移动雷达信号需要在保证现状不变的情况下,新建传输方案至2号航管楼。本文在研究方案的过程中,以保证安全、可靠、平稳为前提,充分验证方案可行性。
2 移动雷达信号传输方案现状
Indra移动雷达位于桂林空管站原发报台台址,距航管楼直线距离2.5km。设备安装在一个方舱内,雷达录取器(EXT)其中两个串口提供的是DDE格式的雷达数据,DDE是INDRA自己的数据格式,不适用于国内目前使用的自动化系统,另外两个串口提供的是ASTERIX格式的雷达数据,ASTERIX是当前……
