I find some errors about sentinel-1 in some fixed areas, where is Rel_orbit 114, frame 144. I think it that maybe the damage of payload of sentienl-1, but the problem only happens repeatedly in a single brust.
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”. However this problem may occur to VV band after (including )“S1A_IW_SLC__1SDV_20210202T121040_20210202T121108_036411_044618_0661”
The picture of the problem are shown in the attachment.
