The Full Form of NAISAR is NASA-ISRO Synthetic Aperture Radar.

sing advanced radar imaging that will provide an unprecedented, detailed view of Earth, the NASA-Indian Space Research Organisation (ISRO) Synthetic Aperture Radar, or NISAR, satellite is designed to observe and take measurements of some of the planet’s most complex processes, including ecosystem disturbances, ice-sheet collapse, and natural hazards such as earthquakes, tsunamis, volcanoes and landslides.

Data collected from NISAR will reveal information about the evolution and state of Earth’s crust, help scientists better understand our planet’s processes and changing climate, and aid future resource and hazard management. The mission is a partnership between NASA and the Indian Space Research Organization.
