| 摘 要： | stolt迁移实现探地雷达三维合成孔径成像具有实现速度快的优点,但stolt迁移有一显著缺点是它不适用于电磁波波速变化的情形,而在探地雷达的应用中电磁波波速变化是实际存在的。本文提出了一种改进的基于stolt迁移的探地雷达三维合成孔径成像方法,该方法能克服普通方法不适用于电磁波波速变化这一缺点。通过对实测数据进行处理,其结果表明所提方法取得了很好的效果。

| Abstract: | Ground penetrating radar three dimension synthetic aperture imaging by stolt migration has a merit of fast processing speed, but there is a distinct shortcoming which is not suitable for variety of electromagnetic wave transmitting velocity, variety of electromagnetic wave transmitting velocity exists in application of ground penetrating radar. This paper proposeds a modified ground penetrating radar three dimension synthetic aperture imaging method based on stolt migration , this method can overcome the shortcomings. the results of processing measurement data show this method is very effective. |
