L-Curve Characteristic Value Correction Iteration Method for SBAS-InSAR Deformation Inversion
Abstract We propose a L-curve characteristic value correction iteration method, using the maximum curvature point of L-curve to determine the final estimation results. The experimental results of SBAS-InSAR deformation inversion show that the L-curve characteristic value correction iteration method can be used to determine a stable estimation result with a small residual, thus improving the accuracy and stability of the estimation result.
