【摘要】：舰载相控阵雷达系统是当前舰载武器系统的重要组成部分,是舰载武器系统中获得战场信息的重要工具,承担着对空中来袭目标的捕获、跟踪等任务。对相控阵雷达系统进行功能仿真,不仅可以对雷达系统的综合性能进行评估,同时可以为相控阵雷达系统的发展提供指导。本文对舰载相控阵雷达系统功能仿真进行研究,希望通过建立完整的仿真模型来提高功能仿真系统的完备性。首先,根据相控阵雷达系统运行机制和工作方式进行分析并制定了仿真系统总体设计方案。同时,本文给出了功能仿真系统的模型组成框图并介绍了各模型的主要功能。其次,本文对功能仿真系统的各组成模型进行了详细的原理分析,结合功能仿真的特点给出了组成模型的详细建模方法,构建了较为完整的功能仿真系统模型库。其中,对功能仿真系统中的信号处理、数据处理以及资源调度模型进行了详细分析。之后,搭建了相应的仿真系统。最后,本文给出了仿真系统软件的具体实现方法,并对仿真系统的终端显示模型进行了说明。通过构建合理的仿真场景和设置雷达系统的仿真参数,对功能级雷达系统进行仿真测试,并给出了误差结果图以及采用两种滤波算法时的仿真结果对比图。同时,我们对仿真结果和雷达在电磁干扰环境下的探测和跟踪精度进行了分析。
[Abstract]:Shipborne phased array radar system is an important part of shipborne weapon system at present. It is an important tool to obtain battlefield information in shipborne weapon system. Tracking and other tasks. The functional simulation of phased array radar system can not only evaluate the comprehensive performance of radar system, At the same time, it can provide guidance for the development of phased array radar system. This paper studies the functional simulation of shipborne phased array radar system, hoping to improve the completeness of the functional simulation system by establishing a complete simulation model. According to the operation mechanism and working mode of phased array radar system, the overall design scheme of simulation system is established. At the same time, the model composition block diagram of functional simulation system is given and the main functions of each model are introduced. In this paper, the principle of each component model of the functional simulation system is analyzed in detail, the detailed modeling method of the composition model is given according to the characteristics of the functional simulation, and a more complete model base of the functional simulation system is constructed. The signal processing, data processing and resource scheduling model in the functional simulation system are analyzed in detail. After that, the corresponding simulation system is built. The terminal display model of the simulation system is explained. By constructing reasonable simulation scene and setting up the simulation parameters of the radar system, the simulation test of the functional level radar system is carried out. At the same time, we analyze the simulation results and the detection and tracking accuracy of radar in EMI environment.
