An Efficient Method of Refraction Points Determination Betweenthe Interfaces of Multi-media
摘要/Abstract
利用电磁波在介质分界面上的折射特性,研究了一种有效确定多层介质分界面上折射点位置的方法.以双层介质为例,介绍了折射点确定原理与常用的"工程算法"的实现,提出了一种双层介质折射点的精确计算方法——"转角法",对各种方法进行了分析比较,并借助工程软件编写相应求解程序对其准确度进行验证.计算结果表明,所提供的计算方法简单有效.
Ground penetrating radar (GPR) is a very practical instrument in the detection and recognition of subsurface targets.The determinat ion of refraction points between the interfaces of multi-media is critical to DAS imaging when the elect romagnetic wave is going through mult-i media,yet there is still not a perfect algorithm to solve this problem.One algorithm for the determination of refraction points of multi-media is presented,which utilizes the integrated refraction relation.It is proved to be very efficient in comparison with the common alg orithms.
