Problem to corregistrate at Antarctica

Microwave Toolbox Interferometry
#1

Hello, I am trying to process an interferometric pair at Antarctica but I cannot co-register two images there (I’ve done it at other places with no problem).

As a first step, I tried to perform a S1 TOPS corregistration with pairs these three images (I tried all combinations, without success):
S1A_IW_SLC__1SSH_20160913T081723_20160913T081751_013031_014A56_6758
S1A_IW_SLC__1SSH_20170628T081725_20170628T081753_017231_01CBF8_C43E
S1A_IW_SLC__1SSH_20190501T081735_20190501T081803_027031_030B4C_CECD
using the 100m REMA dem:

using the first subswath (IW1) and the last two bursts (9 and 10).

As result I get the corresponding stack but the information related to the slave image is empty.

Does anyone know what is going on?
Best!

The first thing please take a look at the following steps until the step of corr. which is your demand, they are steps 3. and 4.

Source of the post : Creating DEM,

The second important thing, Reproject The DEM to the EPSG:4326 , Also be sure that your DEM is covered your study area,

This is your DEM,

Thanks Falah for your answer. The problem was indeed the projection. I expected (incorrectly) NEST to understand different projections.
