【摘要】：随着军事领域技术的不断发展,雷达作为其中的重要角色,其性能要求越来越高,对雷达性能进行分析成为研究和发展的重要方向。计算机和软件技术的快速发展为雷达系统及雷达性能评估的软件仿真提供了强有力的技术支持。而目前对雷达性能的分析仿真多数是根据单独的理论知识所构建的程序块,不具有系统性,且这些程序一般存在可读性、人机交互性差等缺点。因此,将雷达系统不同方面的性能分析进行封装集成,开发一种具有直观交互界面的雷达性能分析软件具有重要的现实意义。本文根据雷达系统性能分析需求,利用MATLAB强大的集成图形用户界面对雷达性能分析软件进行开发和实现。首先对软件总体及其中各模块的需求进行分析,提出了总体设计方案和各模块的设计方案。之后介绍了各模块的基础理论和背景知识,深入地说明了其具体的设计实现原理。天线功能分析模块完成了天线方向图的产生及天线增益等参数的计算功能;地面雷达作用距离分析模块具有手动输入和数据导入两种模式对雷达作用距离进行计算;改善因子及杂波背景下雷达威力分析模块完成了不同因素对改善因子限制的计算及杂波背景下雷达威力分析功能;雷达跟踪精度估算模块应用于距离误差和角度误差的分析估算。同时,展示了各模块开发的设计流程及应用结果,证明了软件的实用性和易操作性。最后,对雷达性能分析软件做出了总结,进一步说明了雷达性能分析软件在雷达系统性能指标分析中的实际应用价值和指导作用。
[Abstract]:With the continuous development of military technology, radar as an important role, its performance requirements are higher and higher. The analysis of radar performance has become an important direction of research and development. The rapid development of computer and software technology provides powerful technical support for radar system and software simulation of radar performance evaluation. Performance analysis and simulation are mostly based on the individual theoretical knowledge of the building blocks. These programs are not systematic and generally have some shortcomings such as readability, poor human-computer interaction, etc. Therefore, the performance analysis of different aspects of radar system is encapsulated and integrated. It is of great practical significance to develop a radar performance analysis software with visual interaction interface. A powerful integrated graphical user interface (MATLAB) is used to develop and implement the radar performance analysis software. Firstly, the requirements of the whole software and its modules are analyzed. The overall design scheme and the design scheme of each module are put forward. After that, the basic theory and background knowledge of each module are introduced. The principle of design and implementation is explained in detail. The antenna function analysis module accomplishes the function of generating antenna pattern and calculating the antenna gain. The ground radar action range analysis module has two modes of manual input and data import to calculate the radar action range. Improved factor and clutter background radar power analysis module completed different factors to improve the factor limit calculation and clutter background radar power analysis function; Radar tracking accuracy estimation module is applied to the analysis and estimation of range error and angle error. At the same time, the design flow and application results of each module are shown, which proves the practicability and operability of the software. The radar performance analysis software is summarized, and the practical application value and guiding function of radar performance analysis software in radar system performance index analysis are further explained.
