中文说明：
地震信号处理，虚同相轴方法预测层间多次波，将数据分成上下两部分，利用相关和褶积的原理预测出层间多次波。预测信号和原始信号在相位和振幅上存在差异，用L1范数匹配法进行匹配，其中，提供了两种方法解病态方程，分别为高斯-赛德尔方法和正则化方法。
English Description：
Seismic signal processing, imaginary phase axis method to predict interlayer multiples, the data is divided into two parts, using the principle of correlation and convolution to predict interlayer multiples. There are differences in phase and amplitude between the predicted signal and the original signal. L1 norm matching method is used to match. Two methods are provided to solve the ill conditioned equation, which are Gauss Seidel method and regularization method
