Problems in TOP SAR

As stated, the selection in SubSwath must be the same for both images. Make a selection in both TOPSAR-Split tabs and the message will disapear.
I however wonder about your image selection. It seems that they are 7 days apart which makes no sense. Only images of same orbit can be combined, please see here:

INSAR / DINSAR - Perpendicular baseline calculation

when you download your data, make sure that both data sets cover the same area, in particular in West-East direction and flight direction. So for interferometry, you cannot combine ascending and descending images, nor images from different tracks For Sentinel-1, for example, these dates are multiples of 6 days away, so 6, 12, 18, 24… So, in my example, you can use the two black images, but not black with red or with blue [image]
