This repository contains scripts for mitigating phase bias in InSAR data. It includes tools for reading data, calculating loop closures, estimating calibration parameters, performing inversion, and correcting interferograms.
-
PhaseBias_01_Read_Data.py: Reads input wrapped ifgs and coherence data. -
PhaseBias_02_Loop_Closures.py: Calculates loop closures. -
PhaseBias_03_calibration_pars.py: Estimates the calibration parameters$a_n$ . -
PhaseBias_04_Inversion.py: Performs inversion for phase bias estimation. -
PhaseBias_05_Correction.py: Corrects interferograms using estimated biases. -
bin/: Contains auxiliary functions used by the scripts. -
config.txt: Configuration file for setting parameters.
- Clone the repository:
git clone https://github.com/YourUsername/InSAR_PhaseBias_Correction.git cd InSAR_PhaseBias_Correction
The test dataset used in this repository originates from one of the islands in the Azores. The full dataset can be accessed through the COMET LiCSAR frame 082D_05125_020000, available at the following link:
