摘要
本文在半空间中。采用地表发射和地表接收的配置－地表反射式（ＳＲＰ），利用ＳＨ波进行衍射层析成象。在Ｂｏｒｎ近似下，导出反演公式并给出模型验算结果。此法属“滤波－反传播”算法一类。对于Ｎ×Ｎ图象的反演，主要用Ｎ次ＦＦＴ完成。
In this paper, with both transmitters and recevers on the surface, we use SH wave for diffraction tomography in half space. Inverse formula is presented under Born approximation and computer simulations are also included. This algorithm belongs to 'filtered back propagation' type for the tecnique. For an N×N image, it needs, mainly, N FFT operations and interpolation free.
