A dedicated U.S. and Indian InSAR mission, in partnership with ISRO, optimized for studying hazards and global environmental change.
The NASA-ISRO Synthetic Aperture Radar (NISAR) mission is a joint project between NASA and ISRO to co-develop and launch a dual frequency synthetic aperture radar satellite. The satellite will be the first radar imaging satellite to use dual frequency and it is planned to be used for remote sensing to observe and understand natural processes of the Earth.
ISRO will be responsible for design and development of S-band SAR, Spacecraft Bus, data transmission system, spacecraft integration and testing. The radar will be launched using the Geosynchronous Satellite Launch Vehicle (GSLV) and ISRO will also be responsible for the in-orbit operations, Minister of State in the PMO Jitendra Singh, who also holds charge of the Space Department, told the Rajya Sabha in a written reply on July 21, 2016. The project is slated to be completed and launched by 2021, parliament was told on Thursday.
Using advanced radar imaging that will provide an unprecedented, detailed view of Earth, the NASA-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.
– L-band (24-centimeter wavelength) Polarimetric Synthetic Aperture Radar
– S-band (12-centimeter wavelength) Polarimetric Synthetic Aperture Radar
In what’s being termed a first of its kind endeavour, NISAR will be able to operate in two frequencies, both in bands lower than KU-Band or AA-Band. While Isro will take care of the S-band radar, expected to have a 12-cm wavelength, Nasa will supply the 24-cm wavelength L-band radar.
