Frequency-wavenumber analysis is a commonly used method in array processing,and has a good effect in seismology and other fields. In this paper,we firstly illustrate the basic principle of F-K analysis and a variety of improved F-K methods,and then present the application of these techniques in array data analysis,including the detection of weak sources,noise characteristic analysis,the extraction of surface wave dispersion curves,the estimation of different array design schemes. Through the overview of these four aspects,we analyze the new progress and problems to be noted in this field,and prospect the potential application of F-K analysis method.
