INSAR Flat-earth Phase Removal Approach Based on DEM to Settlement Area

INSAR Flat-earth Phase Removal Approach Based on DEM to Settlement Area

The difficulties of phase unwrapping was increased with the existence of flat-earth phase removal, at the same time, it covered up the real topographical conditions. In order to solve this problem, the paper presented a method of re-flattening. based on DEM to eliminate flat-earth phase, with the in...
