摘要
雷达作用范围和遮蔽盲区的快速计算和三维可视化是复杂电磁环境研究的重要内容。基于抛物方程建立了雷达探测范围的数学模型,对于三维地形遮蔽雷达作用范围形成的盲区,采用碰撞检测方法进行估算,并利用图形硬件(GPU)的加速功能实现了盲区估算的快速算法。实践证明,快速计算雷达的地形遮蔽盲区可以为用户决策提供支持,具有重要的工程应用价值。
The fast algorithm for estimation and visualizing of radar coverage and shadow plays an important role in the research of electromagnetic information.A mathematic model based on parabolic equation theory is built for estimation of radar shadow,and a new algorithm is proposed to estimate radar shadow affected by terrain,which using collision detection method and running on GPU.Illustrative numerical results are presented,the algorithm for radar shadow is fast,which could provide decision supporting and meets the requirement of application.
