NISAR S-band SAR

Missions → NISAR (Operational)

ISRO S-band synthetic aperture radar payload for NISAR.

Sensor

NISAR S-band SAR is the S-band SweepSAR instrument on NISAR, using active microwave imaging for synthetic aperture radar collection.[1][2][3] The instrument operates in S-band around 3.2 GHz, within a 3.162-3.237 GHz range for the S-band radar context.[1][2] Its SweepSAR mode supports about 242 km swath and 3 m range resolution.[1][2] The S-band mode set includes full and hybrid polarimetric operation, with single, dual and compact-polarisation modes also recorded for the instrument.[2] SAR backscatter, InSAR surface deformation and polarimetric SAR decomposition are demonstrated through NISAR, so buyers should read those as demonstrated uses rather than inferred capabilities.[1][2] NISAR launched on 2025-07-30, and SAR-S utilization is recorded from October 2025 with end of life at or after 2029.[4][2]
