@jun_lu can you help?

The data of the S1 TOPS SLC product are provided in bursts. Therefore you cannot co-register two split SLC products with the normal coregistration operator. You should use S-1 Back Geocoding operator (see image below). This tutorial (Retrieval of digital elevation models from Sentinel-1 radar data – open applications, techniques, and limitations) may be helpful.
