| 摘 要： | 随着图形图像技术、虚拟现实技术的发展,用户对雷达模拟器中雷达图像的逼真程度要求越来越高.为了提高雷达图像的仿真效果,建立了高、低潮状况下的雷达数据以体现不同潮汐状况时雷达图像的差别;设计了遮挡判断方法,从而更准确地判断岸线之间以及岸线内部的遮挡关系;改进岸线回波生成方法,实现了不同类型岸线的不同回波效果;采用展宽目标的方法,实现了岸线内部的填充效果.所做工作已应用到航海雷达模拟器中,仿真效果良好.

| Abstract: | Since the development of image technology and virtual reality technology,users of radar simulators expect higher lifelikeness of synthetic echo images in recent years.In order to enhance the effect of the simulation,several measures are taken: separate radar data sets are built for high and low tides respectively so as to express differences of radar images in different tidal conditions;the occlusion judgment criteria is set up for accurate judgment of the occlusion relations on a coastline and between coas... |
