Mosaic two pairs of SLC image from a common path?

how can I mosaic two pairs of SLC image from a common path and then make them coregistered for interferogram formation and surface displacement determination?

The SLC image pairs
Pair1 ( S1A_IW_SLC__1SDV_20230306T002115_20230306T002142_047516_05B49D_BD40 & S1A_IW_SLC__1SDV_20230306T002051_20230306T002118_047516_05B49D_CDC6 )

Pair 2 (S1A_IW_SLC__1SDV_20230330T002115_20230330T002142_047866_05C070_A605 & S1A_IW_SLC__1SDV_20230330T002051_20230330T002118_047866_05C070_A672)

That’s possible to stitch sequential scenes for the same orbit to produce larger frame, see the interactive Jupyter notebook example in Google Colab: Google Colab
