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.
- NISAR stands for NASA ISRO synthetic aperture radar. It is being developed to take a radar imagery of earth in an unprecedented detail.
- NISAR will use two different radar frequencies – L-Band by NASA and S-band by ISRO.
