InSAR accuracy, precision and line of sight: what the numbers really mean
What InSAR accuracy and precision really mean, why measurements are along the line of sight, and why millimeter sensitivity is not universal accuracy.
How satellite InSAR measures small ground movements: from radar phase to decisions
How does InSAR detect millimeter ground movement? A plain-language walk from radar phase and interferograms to time series and engineering decisions.
Can satellite InSAR show movement in three dimensions?
InSAR measures movement along the satellite's line of sight. Learn how combining viewing geometries and other data builds a fuller picture of 3D motion.
