【摘要】：由于APG-77雷达在F-22战斗机上的成功应用,而且计算机仿真技术应用于雷达算法和系统的实时仿真日渐成熟。本文设计的机载相控阵雷达功能级仿真系统是基于Visual Studio 2010平台,通过对雷达功能模块和系统进行测试,完成了红蓝对抗实时仿真,对于战略战法的研究具有指导意义。本文首先讨论了脉冲重复频率的选择不同,目标落入的杂波位置不同,并且结合了搜索加跟踪、边扫描边跟踪、猝发探测这三种工作方式,提出了红蓝对抗总体方案和单部机载雷达功能级仿真系统的总体构成,规范了系统的输入和输出接口。然后介绍了系统的组成模型及各模型的主要功能,主要阐述了包括相控阵天线模型、坐标转换模型、环境回波功率产生模型、目标检测模型、数据处理模型、资源调度模型、反隐身模型、抗干扰模型等在内的功能级建模原理。文章是基于XML技术来设置初始化参数,并对控制界面和显示界面进行了说明介绍。将搭建好的单部雷达系统扩展成为四个红方飞机对抗四个蓝方飞机,完成了四对四目标势态显示和B显显示;与此同时,为了验证单部机载雷达的性能,先测试天线方向图的正确性,接着测试波位编排的结果和不同天气情况下的气象杂波衰减系数。之后将机载雷达在三种工作模式下的滤波数据进行对比分析,并在探测单目标情况下,对滤波数据的精度、采取反隐身的作用距离变化、添加干扰的距离误差进行了数据分析。仿真结果验证了机载雷达系统的有效性和正确性。本文是基于标准化组件的软件平台,以模块化、标准化、高凝聚、低耦合的思想进行建模,这不仅完善了雷达系统的模型库,而且实现了可快速方便地搭建新的系统,增强了模块的移植功能。
[Abstract]:Because of the successful application of APG-77 radar in the F-22 fighter, and the computer simulation technology is applied to the real-time simulation of radar algorithm and system, the function level simulation system of airborne phased array radar is based on the Visual Studio 2010 platform, and has completed the red and blue confrontation through the testing of the radar function module and system. Real time simulation is of guiding significance for the research of strategic warfare method. Firstly, the selection of pulse repetition frequency is different, the location of the clutter in the target is different, and the three working modes are combined with search and tracking, edge scan tracing and sudden detection, and the overall scheme of red and blue confrontation and the function level imitation of single airborne radar are put forward. The overall composition of the real system, standardizes the input and output interfaces of the system. Then it introduces the composition model of the system and the main functions of each model, mainly including the phased array antenna model, the coordinate transformation model, the environment echo power generation model, the target detection model, the data processing model, the resource scheduling model, anti stealth model, the anti stealth model, and the anti stealth model. The principle of functional level modeling, such as interference model, is set up based on XML technology to set up the initialization parameters and explain the control interface and display interface. The constructed single radar system is extended to four red square aircraft against four blue-square aircraft, and the four to four target state display and B display are completed. In order to verify the performance of the single airborne radar, the correctness of the antenna pattern is tested first, then the results of the wave position arrangement and the attenuation coefficient of the weather clutter in different weather conditions are tested. Then the airborne radar is compared and analyzed in the three operating modes, and the filtering data is refined under the single target detection. The simulation results verify the validity and correctness of the airborne radar system. This paper is based on the software platform of standardized components, modeling with the idea of modularization, standardization, high cohesion and low coupling, which not only improves the radar system. The model library also implements the new system quickly and conveniently, and enhances the transplantation function of the module.
