Problems encountered in using unpackFrame_ENV.py

[zhouhuayun]

hi,all
When I plan to use stackStripmap.py to process ENVISAT_SLC(*.N1) data, I encounter the following problems when using unpackFrame_ENV.py:

Traceback (most recent call last):
File "/share/apps/anaconda3/envs/isce2022/lib/python3.9/site-packages/isce/components/contrib/stack/stripmapStack/unpackFrame_ENV.py", line 95, in
unpack(inps.h5dir, inps.slcdir)
File "/share/apps/anaconda3/envs/isce2022/lib/python3.9/site-packages/isce/components/contrib/stack/stripmapStack/unpackFrame_ENV.py", line 50, in unpack
pc = obj._dopplerCoeffs[::-1]
AttributeError: 'EnviSAT_SLC' object has no attribute '_dopplerCoeffs'

What may be the cause of this?
The orbit files come from here: https://earth.esa.int/eogateway/catalog/envisat-doris-precise-orbit-state-vectors-dor-vor_ax-
The instrument files come from here: https://earth.esa.int/eogateway/instruments/asar/auxiliary-data

Hi! Did you figure out the solution to this issue? I encountered the same problem as yours, and am searching the discussion to find solutions. Appreciated! Frank

Sorry for the late reply, I haven't found the solution yet. Have you found it now?

I corrected it by replacing in unpackFrame_ENV. py:
line 50 pc = obj._dopplerCoeffs [:: - 1] with pc = obj.dopplerRangeTime [:: - 1]

line 54 dops = np.polyval (pc, 2 * rng / Const.c-obj._dopplerTime) with dops = np.polyval (pc, 2 * rng / Const.c-obj.rangeRefTime)

Works!

Hello @vittorio3d I tried your solution and think it works for me too. But, I am unsure about what results to expect after running unpackFrame_ENV.py. I got three data files (.bak, .dat, .dir), and a SLC file with a .vrt and a .XML file. Is only this what I should get?

I am using the tool like this unpackFrame_ENV.py --input Images --output SLC_DIR the Images folder has 35 images from EnviSAT. I did not get the acquisition dates list or any other file - this causes an error in the stackStripMap.py process.

Thanks for any help!

Nice work, thank you.
Thank you very much for your suggestion, but I encountered the following problems in the run_file generated later. I wonder if you have encountered them?

Ciao! I have the same problem...I solved it running stackStripMap without --bbox Vittorio Il giorno dom 4 set 2022 alle ore 14:16 Huayun Zhou < ***@***.***> ha scritto:

Haha, it is a clever solution. So, did you have a smooth process in the later process? According to your practice, there was a mistake in the fifth step(run_05_invertMisreg), which is still being solved.

I encountered this same issue while processing some stripmap data as well, where you able to solve this?

Hello Saeed, I just saw some notifications from you.
It's been a while since I worked on the Envisat project and I don't recall the details pretty well but at the time I followed vittorio3d advice and everything worked for me. Sorry, I don't have any more answers for you.
Best,
Carolina

Hello @vittorio3d <https://github.com/vittorio3d> I tried your solution and think it works for me too. But, I am unsure about what results to expect after running unpackFrame_ENV.py. I got three data files (.bak, .dat, .dir), and a SLC file with a .vrt and a .XML file. Is only this what I should get? I am using the tool like this unpackFrame_ENV.py --input Images/ --output SLC_DIR the Images folder has 35 images from EnviSAT. I did not get the acquisition dates list or any other file - this causes an error in the stackStripMap.py process.

Yes, I got 6 files, three are named as data, and the other three as SLC_DIR. In your case the last three are named 20090116, right?

Should I run unpackFrame_ENV for each SAR image? and to this case, each image must be in a separate folder?
Thanks again!
