The invention discloses a robust spectrum simulation deconvolution method, which is applied to the field of seismic physical exploration, and aims at solving the problems of uncontrollability and instability in the traditional spectrum simulation deconvolution. The hypothesis that the seismic wavelet form is the same as the Ricker wavelet is added, so that the fitting result of the deconvolution wavelet is more controllable, meanwhile, the combined wavelet serves as expected output of deconvolution, boundary robust processing is conducted on a deconvolution operator, high-frequency information of data is controllably and steadily improved, and the method has the advantages of being high in robustness and high in robustness. And the effect of improving the seismic data resolution is achieved. 本发明公开一种稳健的谱模拟反褶积方法，应用于地震物理勘探领域，针对传统谱模拟反褶积中的不可控不稳健的问题，本发明的方法在传统谱模拟反褶积的基础上，加入了地震子波形态和雷克子波相同的假设使得反褶积子波拟合的结果更加可控，同时以组合子波作为反褶积的期望输出，并对反褶积算子进行边界稳健处理，实现了对数据的高频信息可控且稳健的提升，达到了提升地震数据分辨率的效果。
