| 摘 要： | 现有船舶操纵模拟器中雷达图像的模拟多是基于二维海图,生成的图像和真雷达图像之间有一定的差距。根据雷达所在位置及扫描范围,基于三维场景库模拟雷达图像,实时访问场景库获取模型的相关信息。采用圆周扫描方式,以射线组模拟雷达电磁波的波束,并利用射线与三角形求交计算物标的回波位置,在计算回波强度时考虑了物标反射面自身因素的影响。经模拟得出了较好的雷达图像。

| Abstract: | Existing radar image simulation in ship maneuvering simulator is generally based on two-dimensional sea charts,which may lead to some differences between simulated image and real radar image.Radar image simulation based on 3D scene database is proposed.According to the location and scanning range of the radar as well as simulated radar image of 3D scene database,related information of models can be acquired by real time accessing to scene database.A group of rays in a circular scanning mode is applied to si... |
