摘　　要：为解决飞机在低空突防过程中的雷达地形遮蔽盲区快速计算问题,提出了一种基于转盘爬虫对象的快速算法。首先介绍了雷达盲区产生的因素,分析了地形遮蔽和地球曲率盲区的计算模型,然后定义了转盘及爬虫对象,并设计了基于转盘爬虫对象的地形遮蔽盲区计算方法和流程。在此基础上,将雷达地形遮蔽盲区计算结果进行三维建模及可视化,通过典型算例对算法进行对比测试和实验,得到不同高度的雷达地形遮蔽盲区分布图及三维可视化模型,证明了算法的快速性和可行性。To solve the problem of fast computing of the radar terrain masking blind space in the process of aircraft low altitude penetration,a fast algorithm based on dial-reptile objects is put forward.Firstly,the causes of the radar blind space are introduced,and the computing models of terrain masking blind space and earth curvature blind space are analyzed.Then,the dial object and the reptile object are defined.On this base,the computing results are made 3D model and visualized.At last,several typical compute examples are tested on the algorithm,the radar terrain masking blind space on several altitudes and the 3D visual model are got,the validity and efficiency of the presented method is demonstrated.
