Improved phase gradient stacking (IPGS)
The IPGS effectively suppresses atmospheric delay disturbance, topographic residuals, and noise while enhancing local deformation signals. It avoids complicated unwrapping and massive time series analysis. It provides an tool for large-scale, rapid, and reliable detection of geological disasters.
Through this program, we can obtain the gradient stacking results in the SAR coordinate system and the geographic coordinate system respectively. The description of the relevant code is introduced in ipgs_code/help.m
