Crustal Imaging with Noisy Teleseismic Receiver Functions Using Sparse Radon Transform

Abstract

Sparse Radon transform is used to de-noise the Ps-RF and extract Moho-related phases.• Synthetic and data examples show that our approach can drastically reduce the ambiguity of H − κ stacking.• Our approach can be coupled with resonance filtering to improve crustal imaging in reverberant settings.
