摘要
为了适应不同的工作环境,机载预警雷达要分很多种型号;其对应模拟器也要有多种,并且能够实现相互之间的任意切换,而通用平台就是在这种需求下进行开发的;实际开发中,需要解决底层搭建和高效通信这两个关键问题;前者是基于DCS架构,依附以太网搭建而成;后者由于对数据传输实时性,大容量性的有较高要求,则是采用组播技术,并附加NTP模块来弥补网络传播的不确定因素。
In order to adapt to different work environments,airborne early warning radar has many models.The corresponding simulator is the same,and it should be able to achieve arbitrary switching between models.The common platform is designed for this kind of demand.We have to solve two questions during the development：the bottom structure and high-speed communication.The former is based on the DCS architecture,built from the Ethernet attachment.The latter has a high requirement on the real-time data transmission and large capacity.We achieve it with the muhicast technology.We added the NTP＇ s model to make up the weak point on unreliable connection.
