I find some errors about sentinel-1 in the area from Rel_orbit 114, frame 144. I think it that maybe the damage sentienl-1 datas , but the problem only happens repeatedly in the single brust from 2017 to 2021.
In the 4th brust of IW1_VH, the problem has first been found in the file named “S1A_IW_SLC__1SDV_20181203T121030_20181203T121058_024861_02BCD8_5FD6”. ”
Maybe radio transmitters on the ground.
Thanks for your reply. RFI was heard from first time.
However, the RFI problem were not appeared to the InSAR result or SBAS.
By comparing Google Earth, an airport was found there. Thanks again.
