NISAR Provisional Radar Raw Signal Science Data (Version 1)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/nil0brrsd-p1
The NASA-ISRO Synthetic Aperture Radar (NISAR) Level 0B Radar Raw Signal Data (RRSD) product comprises time-sorted unpacked recordings of raw radar echo pulses and related radar instrument telemetry.
Description
It is comparable to the Level 0 raw data products delivered by SAR sensors worldwide (e.g., L1.0 by ESA and JAXA). The RRSD data is focused to a NISAR Radar Single Look Complex (RSLC) product before use in higher-level processing.
A single RRSD product granule consists of radar echoes acquired in the same imaging mode. An observation constitutes all consecutive radar echoes acquired in the same imaging mode. The radar echoes are organized in sub-groups by imaging frequency (A or B), transmit polarization (H, V, L, or R), and receive polarization (H or V) in that order.

The radar echoes of any given frequency and polarization combination are decoded and aligned to adjust for different sampling window start times and can be accessed as a simple two-dimensional raster image. The RRSD product also contains all the instrument telemetry for the entire data take, including the observation.
