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 look-up 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.
