Version 4.01

• Handling of file sizes larger than 4GB on both 32-bit and 64-bit platforms.
• Processing of TerraSAR-X data.
• Improvement of the master-slave overlap calculation. The new algorithm should prevent segmentation faults as sometimes experienced in the past.
• Improvement and speed-up of COMPREFDEM (see Chapter 26) based on a two-step approach. First, the complete DEM is radarcoded and written to a file. Second, the radarcoded DEM is interpolated to the master image geometry using Delaunay triangulation. The overlapping buffers, as in previous versions of Doris, are prevented.
• Simulation of master amplitude image based on DEM ( M_SIMAMP), see Chapter 6.
• Estimation of master timing error based on correlation between master amplitude and simulated master amplitude (M_TIMING), see Chapter 7.
• Estimation of relative timing error between master and slave image (RELTIMING), see Chapter 18.
• DEM assisted coregistration (DEMASSIST), see Chapter 19. For optimal performance, apply after M_SIMAMP, M_TIMING and RELTIMING.
• Coherence estimation after DEM subtraction (default), see Chapter 28.
• Utility construct_dem.sh to download, merge and fill voids of SRTM data (see Section C.2.12).
• Utility doris.process-reset.sh to reset and clean up the processing entries in Doris result files allowing to easily re-run a step or multiple steps (see Section C.2.13).
• Option to output height-to-phase conversion factors (H2PH) based on flat earth (SUBTRREFPHA) or DEM (COMPREFDEM).
• During COARSECORR and FINE coregistration NaN (not-a-number) correlation values, which are mainly due to no data regions at the border of the scene, are eliminated automatically, but the whole list of windows are kept in the doris.log file.
• Coherence output is properly scaled between 0 to 1 range with new option -r of cpxfiddle, see Chapter  C.2.3.
