To covert the complex file to an non-complex intensity image you would use PSIQINTERP found in the Algorithm Librarian.

From version 10.2 onwards, RADARSAT-2 data can be imported using following two methods:

  1. Simply use the product.xml file to open the data in Focus or OrthoEngine. It is supported directly in our Generic Database (GDB) so user do not need to import the data into a PIX file using the CDSAR import program. On pointing to product.xml file in OE or Focus, user will be automatically pointed to select sigma nought, beta or gamma nought callibration type. User can also select 'None' to not apply any kind of callibration to RSAT2 data.
  2. Use FIMPORT in EASI to import Radarsat2 data and apply the calibration. This method will create a PIX file that can be further processed in OE. The FILI parameter must be entered as follows:
  • fili="d:\RS2_SGF\product.xml:Calibration Type:Sigma Nought
  • fili="d:\RS2_SGF\product.xml:Calibration Type:Beta Nought
  • fili="d:\RS2_SGF\product.xml:Calibration Type:Gamma
  • fili="d:\RS2_SGF\product.xml for no calibration.
In OrthoEngine When working with Radar Specific Model, the inclusion of ground control points (GCPs) is optional. Without any GCPs the model is calculated based on the satellites positional information. If required, addition of few GCPs will further refine the model and improve the accuracy. As long as a DEM is included in the project, the images can still be orthorectified without any GCPs.
