Mosaic of two adjacent Sentinel 1A SLC products

Hi, everyone! I’m going to conduct DInSar process with Sentinel 1A SLC products by using SNAP software. But I found my study area covered two SLC products. If I want to obtain the DInSar result of the whole study area, how to mosaic this two products? and what are the optimal steps that I should do?

Thanks.

Best wishes!

S1 Slice Assembly will concatenate the slices into a larger product.
