【摘要】：雷达信息记录仪是现代雷达系统必不可少的辅助设备,它能够实时记录下雷达工作时的综合信息,通过其调阅回放功能可以对历史数据进行重演,包括雷达视频、点迹信息、航迹信息和故障状态等等;通过对历史记录进行统计分析,进一步挖掘记录数据隐含的信息。此外,雷达信息记录仪的诞生,使雷达从简单地搜索跟踪目标设备升级成为既可以搜索跟踪目标,还能对飞行器实验数据进行采集的综合性设备。本文首先对雷达信息记录仪的国内外研究现状、未来发展前景和雷达信息记录仪所涉及的重要技术的发展现状进行了分析。其次在雷达信息记录仪性能分析的理论基础上提出了本课题所设计的雷达信息记录仪的总体设计方案,阐述了其架构及其工作原理,对数据从采集到存储的流程进行了分析。然后依据接口转换这一需求,设计了雷达接口转换板,不仅解决了存储设备光纤接口与雷达终端非光纤接口之间的匹配问题,同时增加了存储设备的通用性。并在对信号采样理论研究的基础上设计了多通道模拟信号采集模块,在对高速串行互连总线协议RapidIO进行研究的基础上设计了光纤通信系统。然后针对RapidIO协议在传输大文件方面的不足提出了三种优化方式:中断方式、手动模式中使用EDMA(增强型直接内存存取控制器)方式和同步模式中使用EDMA方法。在对固态硬盘优缺点分析的基础上设计了高速固态阵列模块,突破了单块固态硬盘在记录带宽和容量方面的限制。并设计了以高速阵列模块为重要组成部分的多通道存储单元和由多块多通道存储单元级联而成的高速数据存储设备,对雷达信息记录仪的具体功能,如数据采集、回放等,从原理和实现方式上进行了阐述。最后研究分析了雷达信息记录仪的软件系统。阐述了记录软件、数据协同软件和数据下载软件等三大子系统,并对各个子系统的实现原理、系统的软件界面、界面上的各个功能模块进行仔细分析。通过系统软件对记录的数据和回放的数据进行比较分析,验证该雷达信息记录仪系统实现了雷达回波数据存储的功能,各项性能满足设计需求。
[Abstract]:Radar information recorder is an indispensable auxiliary equipment in modern radar system. It can record the comprehensive information of radar working in real time, and repeat the historical data through its readback function, including radar video and spot trace information. Track information and fault state, etc.; through the statistical analysis of historical records, the hidden information of recorded data is further mined. In addition, the birth of radar information recorder, The radar has been upgraded from a simple searching and tracking device to a comprehensive equipment which can not only search and track the target, but also collect the experimental data of the aircraft. Firstly, the present research situation of the radar information recorder at home and abroad is discussed in this paper. The future development prospect and the development status of the important technologies involved in the radar information recorder are analyzed. Secondly, based on the theory of the performance analysis of the radar information recorder, the radar information recorder designed in this paper is put forward. The overall design of the. This paper expounds its structure and working principle, and analyzes the flow of data acquisition and storage. Then, according to the requirement of interface conversion, the radar interface conversion board is designed. It not only solves the problem of matching between optical fiber interface of storage device and non-fiber interface of radar terminal, but also increases the generality of storage device, and designs a multi-channel analog signal acquisition module based on the research of signal sampling theory. Based on the research of high-speed serial bus protocol (RapidIO), this paper designs an optical fiber communication system, and then proposes three optimization methods: interrupt mode, which aims at the deficiency of RapidIO protocol in transmitting large files. EDMA (enhanced Direct memory access Controller) is used in manual mode and EDMA is used in synchronous mode. Based on the analysis of advantages and disadvantages of solid-state hard disk, a high-speed solid-state array module is designed. This paper breaks through the limit of recording bandwidth and capacity of single solid-state hard disk, and designs a multi-channel memory cell with high speed array module as an important component and a high-speed data storage device composed of cascaded multi-block and multi-channel memory cells. The specific functions of radar information recorder, such as data acquisition, playback and so on, are expounded from the aspects of principle and realization. Finally, the software system of radar information recorder is studied and analyzed, and the recording software is expounded. Data collaboration software and data download software are three subsystems, and the realization principle of each subsystem, the software interface of the system, Each function module on the interface is analyzed carefully. By comparing and analyzing the recorded data and the playback data by the system software, it is verified that the radar information recorder system has realized the function of radar echo data storage. Performance meets design requirements.
