Purpose
This panel enables to change the preferences of the SAR Spaceborne import tools.
Parameters
Sentineo Make mosaic same track
If this option is set and all the files in the input file list are acquired in succession on the same track, the output will be one single _slc_list with only one .split_bursts folder (for each polarization).
Make power QL
A multilooked power image is created in case of SLC import.
Sentinel Thermal Noise Removal
By setting this flag the software will remove the thermal noise from the Sentinel-1 SAR image.
Removing thermal noise is required to normalize the backscatter signal within the entire SAR image, which is essential to both qualitative and quantitative use of SAR data.
Thermal noise is most obvious in cross-polarization SAR images, such as VH or HV, and SAR images with low backscatter.
Apply Calibration Constant
The calibration constant is applied (if available). Note: this has no effect of phase values.
Fill dummy during import
Possibility to replace invalid backscatter pixel values with random low values.
Capella SLC Estimate Doppler from Raster
If set to true, the doppler value is estimated based on the raster data and overwrite. Please see the General Tools/Data and Quality Analysis/Doppler Estimation tool for more information.
Please note: in case the doppler values are set to zero in the sml file, the provided doppler parameters are probably wrong. This wrong behavior is specifcally verified interferometry Spotlight
CSG Full-Pol Channel
If set to true, the four polarization channels are coregistered with respect to the first polarization inserted through the tool interface. The image can be then used to perform polarimetric analysis. The orginal data has native channel alignment issues, and the different polarizations of the same acquisition are not aligned.
