【摘要】：随着雷达以及各种高新技术的发展,雷达在国防、航天、军事、通信等各方面的应用越来越普及。但是雷达的功能越来越复杂,也使得雷达设备的测试和验证很不方便,雷达回波模拟技术应运而生。雷达回波模拟器拥有很多得天独厚的优势,方便、灵活、经济,还能重复应用,很多雷达研究机构都将其作为一种必要的工具来研制雷达。本文以专用于机载雷达测试的XX雷达回波模拟器项目为背景,从理论出发,首先研究了雷达目标基本特性,然后结合项目需求,建立了回波和干扰信号基本模型,重点讨论了欺骗干扰的几种拖引方式,最后对整个项目的系统组成进行了分析,设计并实现了一套完整的系统控制软件,并给出了整个系统的调试结果。XX雷达回波模拟器功能强大,可以同时产生目标、杂波、以及不同干扰所引起的回波。其控制软件可以对模拟器的每个功能单独控制,也能统一分配任务,所以其结构也非常复杂。本文采用模块化思想对控制软件进行设计,对每一个模块的细节都展开了深入的讨论,包括需求分析、结构设计与最后的实现。然后给出了每个模块的软件流程图,并采用UML图来详细解释每个模块的内部结构以及某些模块之间的层次关系。本文研究的控制软件严格按照面向对象编程的软件设计思想,结合设计模式和三层架构的层次结构,遵循“高内聚,低耦合”的原理,让整个软件系统更加模块化,系统化,也更加方便了系统的升级与优化。采用多线程编程与异步通信的原理,实现不同模块之间的数据传输。
[Abstract]:With the development of radar and all kinds of high-tech, radar is more and more popular in national defense, spaceflight, military, communication and so on. However, the function of radar is becoming more and more complex, which makes the testing and verification of radar equipment very inconvenient, and radar echo simulation technology emerges as the times require. Radar echo simulator has many advantages, such as convenience, flexibility, economy and repeatability. Many radar research institutions use it as a necessary tool to develop radar. In this paper, based on the project of XX Radar Echo Simulator, which is specially used for airborne radar testing, the basic characteristics of radar target are studied firstly, and then the basic model of echo and jamming signal is established according to the requirements of the project. Several towing methods of deception interference are discussed emphatically. Finally, the system composition of the whole project is analyzed, and a complete system control software is designed and implemented. The debugging result of the whole system is given. Xx radar echo simulator is powerful, which can produce the target, clutter and echo caused by different jamming at the same time. Its control software can control each function of simulator separately and assign tasks uniformly, so its structure is very complex. In this paper, the modularization idea is used to design the control software. The details of each module are discussed in depth, including requirement analysis, structure design and final implementation. Then the software flow chart of each module is given, and the UML diagram is used to explain the internal structure of each module and the hierarchical relationship between some modules in detail. The control software studied in this paper is strictly in accordance with the software design idea of object-oriented programming, combines the design pattern and the hierarchical structure of three layers, and follows the principle of "high cohesion and low coupling", which makes the whole software system more modular and systematic. Also more convenient system upgrade and optimization. The principle of multithread programming and asynchronous communication is adopted to realize data transmission between different modules.
