InSAR SBAS Time Series Tool

2 minute read

Published:

The program is written in C++ enabling multiprocessing through OPENMP. The time series inversion is calculated by a general Gauss-Markov linear model (e.g., weighted least square) and then filtered in the frequency domain by FFTW. The estimation is run on a pixel-by-pixel basis and each pixel can be estimated in parallel, therefore it is expected to run fast when OPENMP is enabled.

Published:

This is a InSAR time series analysis tool based on simple stacking with robust least squre (to delete outliers), including phase closure check (unwrapping error) and orbital ramp removal.
