Product Overview¶
The RSLC product is in the zero-Doppler radar geometry convention. The output image is on a grid characterized by constant azimuth time interval and one-way slant range spacing, and all the primary image layers for a multi-polarization or multi-frequency product are generated on a common time-slant range grid. The output grid is also characterized by a fixed starting slant range, azimuth time interval, and slant range spacing values for easy interpolation.
The complex backscatter values of the RSLC are Digital Numbers (DNs) with secondary layer Lookup Tables (LUTs) provided to convert to beta-naught, sigma-naught, and gamma-naught radiometry. These radiometric correction LUTs are defined for the ellipsoid, not for the local terrain.
All standard (i.e., not urgent-response) products are processed using the Medium-fidelity Orbit Ephemeris (MOE) product for forward processing and the Precise Orbit Ephemeris (POE) product for reprocessing campaigns.
