【摘要】：雷达和通信在硬件结构、系统原理等方面具有一定的相似性,将二者进行设备整合、共享,不仅可行而且能节约资源成本。雷达通信一体化理念既符合现代科技的发展方向,也是未来电子信息系统的发展趋势。而使用软件无线电技术能够提高不同系统之间的互操作性。因此,将软件无线电技术研究和雷达通信一体化技术研究相结合具有重大意义。通用软件无线电外设是目前研究软件无线电系统常用的硬件平台,本文将基于通用软件无线电外设平台展开雷达通信一体化技术的研究。文章首先对通用软件无线电外设实验平台的工作机制进行研究,通过对硬件资源、系统配置、控制方法、射频电路、VITA-49协议等方面的分析,验证了使用通用软件无线电外设平台进行一体化实验的可行性。其次通过对雷达通信一体化关键技术的研究,结合具体的实验条件,确定了采用分时体制的一体化系统设计方案。文章最后对雷达通信一体化系统进行方案设计,并配合通用软件无线电外设硬件平台和GNU Radio应用软件进行一体化系统的模块化验证。将系统整体设计划分为三个层次进行设计与验证,分别为时序控制模块、通信功能模块和雷达功能模块三个部分。上位机通过软件方式实现对通用软件无线电外设实验平台接收和发送状态的切换控制;使用GNU Radio搭建流图实现对通信功能模块的可行性验证;通过对接收、发送线程中时间信息的获取验证雷达功能模块的可行性。通过对实验结果的分析,本文所设计的雷达通信一体化系统具备实现雷达测距的功能,并且在实际测试环境下具备一定的通信能力。
[Abstract]:Radar and communication have some similarities in hardware structure and system principle. It is not only feasible but also cost saving to integrate and share the two equipments. The idea of radar communication integration conforms to the development direction of modern science and technology. It is also the development trend of electronic information systems in the future. And the use of software radio technology can improve the interoperability between different systems. It is of great significance to combine the research of software radio technology with the research of radar communication integration technology. In this paper, the research of radar communication integration technology based on the general software radio peripheral platform will be carried out. Firstly, the working mechanism of the general software radio peripheral experimental platform will be studied, and the hardware resources, system configuration and control methods will be studied. The analysis of VITA-49 protocol of RF circuit verifies the feasibility of using general software radio peripheral platform to carry out the integrated experiment. Secondly, through the research of the key technology of radar communication integration, combined with the specific experimental conditions, Finally, the paper designs the integrated radar communication system. With the general software radio peripheral hardware platform and GNU Radio application software, the integrated system is verified by modularization. The overall design of the system is divided into three levels for design and verification, respectively, which are timing control modules. The communication function module and the radar function module are three parts. The upper computer realizes the switch control of the receiving and transmitting state of the general software radio peripheral equipment experimental platform by the software method. The feasibility of communication function module is verified by using GNU Radio stream diagram, the feasibility of radar function module is verified by acquisition of time information in receiving and sending thread, and the experimental results are analyzed. The integrated radar communication system designed in this paper has the function of realizing radar ranging and has certain communication ability in the actual test environment.
