摘　　要：探索一种新的基于体素模型的雷达地形数据三维表示方法,该方法将障碍物探测雷达获取的地形三维回波数据作为体素,通过有约束的自适应分形扩展方法进行空数据的插补,生成连续的三维地形数据,然后由6自由度体素描述方法进行三维模型的映射,解决三维绘制中的场景遮挡问题,最终通过纹理混合的实时渲染方式生成最终的三维地形图像。通过对实际数据验证表明,该方法可生成逼真的三维地形,相比O penGL的绘制方法,提高了雷达数据的可视化效率。Radar scanning terrain data can be produced and plotted in real-time by using a voxel model. A new three-dimensional method for presenting radar terrain data is proposed based on the voxel model in this paper, which sets radar echo wave from terrain as voxel. Continuous three-dimensional terrain data is generated by using constraint adaptive fractal extending inter- polation. Then the terrain model is mapped by using six degree of freedom（6-DOF） voxel pre- senting method to handle occlusions in three-dimensional plotting. The final three-dimensional terrain image is generated by the mixed texture. Actual data from radar shows that the pro- posed method can simulate vivid three-dimensional terrain and improve the display efficiency of the radar data.
