大间距地震数据重建方法研究
|
摘要
介绍了一种基于稀疏约束最小二乘方法的大间距地震道数据重建方法,通过对大间距地震数据空间加滑动窗口,对每个窗口的数据结果采用预测误差算子计算加权系数进行加权叠加处理而得到空道的结果,通过试验表明,该方法能够用来进行大间距地震道数据的重建.
In this paper,wo show a method to reconstruct large gap seismic data based on sparse constraint least square method.The large sampled data were divided into many spatial windows and then we reconstruct it in each window and stack the outcomes by the weighted method.The result show that the method can be used to reconstruction large gap seismic data.
