【摘要】：巡飞弹将无人机技术与弹药技术相结合,在信息化作战体系中具有独特优势。巡飞弹地面站是整个巡飞弹系统的控制中心,而航迹监控系统作为地面站的核心组成部分,对巡飞弹飞行航迹的规划、控制与监视起着至关重要的作用。本文对巡飞弹在突防阶段与侦察阶段的飞行航路进行分析,将GIS技术、视景仿真技术与通信技术相结合,开发一套集航迹规划、航迹更新、航迹监视、姿态还原与任务回放于一体的巡飞弹地面站航迹监控系统。本论文主要内容如下:1.战场环境建模。首先对作战环境进行分析,给出一种基于高程信息的地形构造方法,然后针对巡飞弹飞行时的威胁要素,构建雷达、高炮与防空导弹三大威胁源的等效空间模型,为航迹规划提供环境依据。2.飞行航迹规划。对突防阶段的三维搜索空间进行分析,以最小航迹代价值为目标建立基于SAS算法的航迹规划方法;对侦察阶段的飞行航道进行分析,以最小旁向重叠率为目标得到三种固定模式下的航路点计算公式。3.航迹监控系统设计。依据航迹监控系统功能需求对整个系统进行模块化设计,利用GIS技术实现对巡飞弹的导航监控;利用三维视景技术实现实时姿态的虚拟仿真;利用通信数据链技术实现巡飞弹与各地面模块之间的数据交互。测试结果显示该系统能够准确提供地图导航功能,满足巡飞弹在不同阶段的航迹规划与航迹更新任务,能够实时接收飞行过程中的航迹状态数据并完成在视景计算机中的姿态复现。整个系统运行良好、可靠性高,可以为巡飞弹执行巡弋任务提供保障。
[Abstract]:Patrol missile combines UAV technology with ammunition technology, and has unique advantages in the information warfare system. The ground station of patrol missile is the control center of the whole patrol missile system, and the track monitoring system is the core component of the ground station. The planning, control and monitoring of cruise missile flight path play an important role. This paper analyzes the flight path of cruise missile in the phase of penetration and reconnaissance, and combines GIS technology, visual simulation technology and communication technology. A track monitoring system for cruise missile ground station is developed, which integrates track planning, track updating, track monitoring, attitude restoration and mission playback. The main contents of this paper are as follows: 1. Battlefield environment modeling. Firstly, the combat environment is analyzed. A method of terrain construction based on elevation information is presented, and then the equivalent space model of radar, anti-aircraft gun and anti-aircraft missile is built according to the threat elements of cruise missile. Provide environmental basis for route planning. 2. Flight path planning. Analysis of 3D search space in penetration phase, establishment of track planning method based on SAS algorithm, analysis of flight path in reconnaissance phase, Taking the minimum side-direction overlap rate as the target, the formula of calculating the route points in three fixed modes is obtained. Thirdly, the track monitoring system is designed. According to the functional requirements of the track monitoring system, the whole system is designed by modularization. The navigation monitoring of cruise missile is realized by GIS technology, and the virtual simulation of real-time attitude is realized by using 3D scene technology. The communication data link technology is used to realize the data exchange between the cruise missile and the local surface module. The test results show that the system can accurately provide map navigation function and meet the task of route planning and track updating in different stages of the cruise missile. It can receive the flight track state data in real time and complete the attitude reappearance in the visual computer. The whole system runs well and has high reliability, which can provide the guarantee for the cruise mission of the cruise missile.
