摘要
研究了基于Hartley变换的叠前深度偏移方法。根据Fourier变换与Hartley变换的内在关系 ,具体推导了裂步Hartley变换 (SSH)的叠前深度偏移公式。对Marmousi复杂构造模型和某区的实际资料进行了计算 ,取得了良好的成像效果。表明了本方法及相应算法的正确性 ,它是一种高精度的偏移方法 。
The prestack depth migration method based on Hartley transform is investigated. The split-step Hartley(SSH) transform formulae for prestack depth migration are derived in detail based on the inherent relationships between Fourier transform and Hartley transform. Numerical calculations on Marmousi model and real data yield good imaging results which proves the correctness of the method and its algorithm. The method is a high precise migration method and is applicable for real seismic data processing.
