NASA-ISRO SAR (NISAR) is a joint collaboration for a dual-frequency L and S-band SAR for earth observation.
Indian Space Research Organisation (ISRO) has completed development of a Synthetic Aperture Radar (SAR).
It is capable of producing extremely high-resolution images for a joint earth observation satellite mission with the National Aeronautics and Space Administration (NASA).
“NISAR will be the first satellite mission to use two different radar frequencies (L-band and S-band) to measure changes in our planet’s surface less than a centimetre across.
NASA and Bengaluru-headquartered ISRO signed a partnership on 2014, to collaborate on and launch NISAR.
NASA is providing the mission’s L-band SAR, a high-rate communication subsystem for science data, GPS receivers, a solid-state recorder and payload data subsystem.
ISRO is providing the spacecraft bus, the S-band radar, the launch vehicle and associated launch services for the mission.
