摘　　要：为了解决当前雷达情报传输中存在的问题,提出一种利用IP宽带网络传输雷达情报的系统,设计了本传输系统的关键设备———采用ARM处理器的嵌入式网关。利用专用芯片进行了串口电路的扩展,解决了雷达情报接收中的多串口通信问题;通过裁减、移植嵌入式实时操作系统RTLinux,提高了嵌入式网关对雷达情报处理和传输的实时性和可靠性;在嵌入式操作系统的基础上,利用Socket网络编程,最终实现了雷达情报在IP宽带网上的正常传输。在实验室内,对系统进行测试验证,结果表明,该嵌入式网关能够顺利地对多个串口输入的数据进行处理和转发,在广域网内实现了数据的实时、高速、可靠传输,满足雷达情报传输的要求。To solve the problem in transmission of radar information, a new radar information transmission system based on IP broadband network is introduced. An embedded gateway using ARM processor was designed, which was the key equipment of this system. A special chip was used to solve the problem of multiple serial ports communication in radar information receiving. The embedded operating system RTLinux was reduced and transplanted to improve the real-time performance and reliability. On the basis of the operating system, the Socket network program was applied to realize the radar information transmission in the IP broadband network. In the laboratory, the system was tested, the result showed that the embedded gateway can process and transmit the data received by multiple serial ports successfully, and satisfy the requirements of radar information transmission.
