intinya adalah :

  • co-register scenes
  • calculate baselines
  • create interferogram and extract phase information
  • correct for sensor movement, flat earth removal, athmosphere, etc.
  • convert differential phase to absolute phase differences
  • phase unwrapping
  • phase to height conversion
  • correct for absolute elevation, phase jumps, etc.

dari SAR menuju ke DEM memang sangat kompleks, tapi bisa dilakukan :

toolnya bisa pake buatan ESA
