基于GIS战场环境传感信息的可视化研究

Sensor Information's Visual Research of Battlefield Environment Based on GIS

现有的地理信息系统仅给出了地形、地貌数据,不能满足雷达、红外等传感器成像仿真的需要。基于此本文提出了一种在建立地形、地貌及其战场环境传感信息基础上,利用雷达、红外传感器对战场环境进行可视化仿真的方法。该方法首先是在分析地理信息系统的前提下,讨论了战场地形模型的建立方法,并给出了战场人文目标模型的建模技术,建立了战场地形和三维实体模型;在分析合成孔径雷达和红外成像的原理的基础上,建立了雷达成像仿真所需的传感信息数据;最后结合视景仿真软件Vega的雷达成像模块RadarWorks进行了合成孔径雷达成像仿真。仿真结果表明了该方法的有效性,同时该方法也是对现有地理信息系统的补充和完善。

The current available Geographic Information System（GIS） only gives out the geographic data,which does not satisfy the requirement of sensor image simulation,such as the radar and infrared etc.Based on this,this paper gives out a new method of battlefield＇s visual simulation using radar and infrared sensors,and the method is based on the foundation of sensor information.Firstly the battlefield terrain building method and the technology of 3D modeling are discussed based on the analysis of GIS.Secondly based on the analysis of SAR imaging simulation principle and the theory of infrared imaging simulation,the sensor information data of SAR imaging and infrared imaging simulation are built.Finally the simulation results of SAR imaging and infrared imaging are given out using view simulation software,Vega＇s radar imaging module,RadarWorks,and infrared imaging module,SensorVision.The simulation result shows the effectiveness of the method.At the same time the method is a supplement for GIS＇s.
