A Spectral-Domain Pseudo-Inverse Method for True 3D Gravity Inversion
Shengchang Chen
The main difficulty in 3D gravity inversion is that surface observations lack vertical wavenumber information, making the problem underdetermined and depth resolution poor. Buildin…

A Spectral-Domain Pseudo-Inverse Construction Method for Unitary Diagonalizable Linear Inverse Problems
Shengchang Chen
The paper proposes a spectral‑domain construction of a stable pseudo‑inverse for large linear inverse problems whose system matrix is unitary‑diagonalizable, using regularization f…
