SAR vs InSAR: the difference between radar images and movement measurements
SAR creates radar images. InSAR compares radar phase to measure ground displacement. Learn the difference and why it matters when buying satellite data.
What is InSAR? A practical introduction to satellite ground movement monitoring
InSAR uses repeated radar satellite observations to measure how the ground moves over time. Learn what it measures, where it helps and where it has limits.
NISAR vs InSAR: what is the difference?
NISAR is a NASA-ISRO radar satellite. InSAR is a measurement technique that can use data from many satellites. Here is why the difference matters.
Why engineers and asset managers should understand InSAR
InSAR gives engineers and asset managers spatial and historical movement evidence for design, maintenance and investigation decisions. Here is how to use it.
