NISAR Beta Geocoded Single Look Complex Product (Version 1)

The NASA-ISRO Synthetic Aperture Radar (NISAR) Geocoded Single Look Complex (GSLC) product is a Level 2 product derived from the Level 1 Range Doppler Single Look Complex (RSLC) product by geocoding the input RSLC into a geocoded map coordinate system such as the UTM/Polar stereographic projection system. The geocoding is performed by inverse mapping of the map coordinates with their topographic heights into the radar coordinate system and interpolating the radar signal at the radar location corresponding to the map coordinate.

Phase preserving complex interpolation projects the data onto a uniformly spaced, north-south/east-west aligned geographic grid. The phase of the GSLC product is flattened for the orbit used in the RSLC processing. The phase flattening removes the topographic phase contribution in the GSLC. Consequently, cross-multiplying two GSLC products will result in an interferometric phase flattened interferogram.

The products in this collection are considered Beta products and are intended to enable users to gain familiarity with the parameters and the data formats. Beta products are not intended for use in scientific research.
