摘要
为了实现无人机视景仿真训练中合成孔径雷达(Synthetic aperture radar-SAR)载荷的仿真,本文采用开源仿真平台OpenSceneGraph(OSG),设计一种SAR雷达图像仿真的方法。该方法在OSG的基础上,采用GLSLang(OpenGL Shading Language)渲染技术,解决雷达图像的渲染,并实现雷达图像的地面站显示。最后设计仿真流程并对该方法进行仿真验证。仿真结果表明,本文设计的方法能够实现无人机SAR雷达视景仿真的功能,为无人机雷达载荷视景仿真提供一种新的技术途径,并在某型无人机仿真训练中得到应用。
In order to solve UAV＇s SAR radar-payload visual simulation in operational training,a design of SAR simulation images is suggested based on OSG simulation bed,which solves rendering of radar images using GLSL rendering technology and the radar terminal display in UAV Ground Control Station（GCS）.The simulation result shows that the design,which is used in a UAV＇s operational training,can gain visual simulation of UAV＇s radar-payload with SAR mode,and provides a new technical method for the visual simulation of UAV＇s radar-payload.
