A Review of H-k Stack Method of Receiver Function

Since Zhu and Kanamori proposed the receiver function H-k stacking method, it has become a conventional tool to deal with the crustal structure. In the process of using and developing the method in the past 20 years, people's understanding of the method has been deepened gradually, and at the same time, the method has been developed and improved. This paper first introduces the basic principle of this method, and then summarizes the influence of P-wave velocity, seismic phase weight, Gaussian coefficient, inclined interface, anisotropy, sedimentary layer and internal interface on this method. Finally, the practice of this method in mainland China is summarized, and the current research results are summarized, and the next research direction is discussed.
