【摘要】：雷达的目标显示及控制终端作为雷达系统的重要组成部分,必须能够对雷达系统进行精确控制,负责显示雷达目标信息、状态信息、GPS定位等信息,是操作员与雷达系统进行交互的平台。本文开展基于嵌入式系统的雷达显控终端的研究,采用先进的嵌入式技术,设计实现雷达显控的智能终端,对提高便携式近程战场侦察雷达的性能有重要意义。 本文首先对雷达显控终端的功能需求进行综合分析,提出嵌入式雷达显控终端的主要功能和技术性能指标,设计了基于嵌入式技术的雷达显控终端硬件总体方案和软件系统架构。选择三星Exynos4412处理器作为嵌入式系统的核心部件,以此为基础建立硬件平台。其次,针对系统实时性的要求,选择嵌入式Linux作为本系统的操作系统,并搭建基于目标机-宿主机模式的交叉编译环境。作为系统设计的重要内容,显控终端软件采用模块化设计,包括：基于Qt/Embedded的人机交互界面设计；雷达参数设置模块设计；雷达状态显示模块设计；B显与P显两种显示模式下雷达目标显示模块的设计；基于以太网与串口两种通信方式的通信模块设计。最后,将显控终端软件移植到硬件平台进行系统联调,充分验证了嵌入式显控终端系统设计的正确性。

In this paper, the research of radar display and control terminal based on embedded system is carried out, and the intelligent terminal of radar display control is designed and realized by using advanced embedded technology, which is of great significance to improve the performance of portable short-range battlefield reconnaissance radar. In this paper, the functional requirements of radar display and control terminal are comprehensively analyzed, the main functions and technical performance indexes of embedded radar display and control terminal are put forward, and the overall hardware scheme and software system architecture of radar display and control terminal based on embedded technology are designed. Samsung Exynos4412 processor is selected as the core component of embedded system, on the basis of which the hardware platform is established. Secondly, in order to meet the real-time requirements of the system, embedded Linux is selected as the operating system of the system, and a cross-compiling environment based on the target machine-host mode is built. As an important part of the system design, the display and control terminal software adopts modularization design, including: human-computer interaction interface design based on Qt/Embedded; radar parameter setting module design; radar state display module design; radar target display module design under B display and P display mode; communication module design based on Ethernet and serial port. Finally, the software of the display and control terminal is ported to the hardware platform for system adjustment, which fully verifies the correctness of the design of the embedded display and control terminal system.
