| 摘要: |
| 未来数字化战场迫切需要表现复杂环境影响下的三维雷达作用范围，目前研究多限于二维，而三维表现又受限于速度，为此提出一种硬件加速的三维表现方法。在构造环境影响下雷达电磁波损失三维数据场的基础上，利用硬件加速的等值面提取算法建立雷达作用范围的三维模型，并将其表现到战场环境中。在普通微机上针对典型雷达的实验中，克服了二维表现不直观以及三维表现慢的缺点，形象地展示了地形大气等环境影响下三维作用范围，从而为用户提供决策和感官支持。 |

| Abstract: |
| Future digital battlefield is crying for a 3D representation of the radar coverage affected by complex environment such as terrain, ocean and weather. However, recent researches still focuses mainly on 2D representation while the existing 3D methods are always embarrassed by their low computation speed, a new hardware accelerated 3D representation method was put forward in this paper. Based on the constructed 3D data field of EM loss affected by environment, a hardware accelerated algorithm was designed to extract the isosurface for building the 3D radar coverage model. Then the model was represented into digital battlefield. In the experiment on popular PC and for typical Radar, the 3D radar coverage affected by terrain and atmosphere was vividly visualized in time. The result has overcomed the implicity of 2D method and the slowness of 3D method, thus providing excellent decision and sense supporting for users. |
