Error- input should be single look complex SLC product

hello
i am trying to create an INSAR product but i am getting this error “input should be single look complex SLC product”

i am new to this can anyone help me with what i am doing wrong and how i can correct it

plz let me know if more details are needed

Please provide more information:

  • What data are you using (Sensor, product, date)?
  • Which steps did you already undertake in SNAP?
  • What InSAR product are you aiming at?

1)i am using sentinel 1 data
S1A_IW_GRDH_1SDV_20160728T051116_20160728T051141_012344_013391_644F.SAFE

S1B_IW_GRDH_1SDV_20161107T051036_20161107T051101_002848_004D2E_A040.SAFE

2)i have created subset of target location and performed coregistration

3)i am planning to perform DInSAR

SAR interferometry requires the complex information of the backscattered radar signal.
GRDH products no longer contain this complex information. You will have to download the SLC products.

Please have a look at the interferometry tutorial first:

thank you for your help

hello
i am trying to perform the tutorial you have mentioned above but when i am trying to deburst i am getting operation error “the specified region if not null must intersect with the image’s bound .” i made a subset before the deburst step as i am getting java heap error other wise . can you plz tell me what i am doing wrong or how to correct it .

data used

I don’t think that subsetting a S-1 IW SLC is even possible - my understanding is that it should give you an error instead(?). You can work with one subswath only by applying TOPS Split first, this will save you memory.

Hi mengdahl,

Cannot I use both multilooked corregistration images and interfergrams to export to stamps? when I did it, I also got the must put in SLC products error. I tried to use mt_prep_snap too. Seems there’s no multi look option which means I would spend much time doing error estimation in stamps. Could you please tell me which step I can do multilook?
