Which SAR satellites support InSAR? A guide to current radar missions
A guide to the main radar satellite missions used for InSAR across X-, C-, S-, L- and P-band, and how to judge which suit your monitoring needs.
What is NISAR? A guide to the NASA-ISRO radar mission
NISAR is the NASA-ISRO radar satellite launched in 2025. Learn what its L- and S-band instruments measure and what it means for ground motion monitoring.
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.
S-band InSAR: what NISAR's S-band radar adds
S-band sits between C- and L-band. Learn what NISAR's S-band radar offers for InSAR and how to judge whether it suits your monitoring needs.
L-band InSAR: when a longer radar wavelength gives you an advantage
L-band InSAR can keep useful coherence over vegetated and changing surfaces. Learn where the longer wavelength helps and which missions provide it.
LiDAR vs NISAR: comparing a survey method with a radar mission
LiDAR uses laser pulses to map surfaces in 3D. NISAR is a NASA-ISRO radar satellite whose data supports InSAR. Learn how they differ and work together.
