The invention provides a
reconstruction method of
seabed earthquake data. On the basis of the sparsity of the
seabed earthquake data, irregular
curvelet transform is used to extract a sparse characteristic of the earthquake data, a sparse
curvelet coefficient that satisfies a constrained condition is obtained via multiple times of iteration, and regular inverse transformation is carried out on thesparse
curvelet coefficient to obtain the reconstructed
seabed earthquake data. Thus, the seabed earthquake data can be reconstructed effectively, and
noise interference can be removed.
