Phase discontinuity Issue in MultiMasterInSAR but not in Interferogram Operator

Microwave Toolbox Interferometry
1

The workflow for both operator I used is with two images using three burst of swath IW1

  1. MultiMasterInsar

TopSAR Split>BackGeocoding>ESD>Add Elevation > MultiMasterInsar ( Top Image)

  1. Interferogram

TopSAR Split>BackGeocoding>ESD>Interferogram (Botom Image)

The Multimaster produced phase output has several discontinuity among adjacent bursts but Interferogram operator output have continous phase. Is this bug in MultiMasterInsar that cannot resolve coregistration though i applied ESD. How to solve it?

Which version of Snap are you using? If it is the latest version, ie SNAP 13, did it used to work in Snap 12 or earlier?

I figure it out, first I need to deburst and then use the MultiMasterInSAR operator. Thank you though. I appreciate it.
