Good afternoon, dear colleagues. I am a representative of the Ukrainian company GeophysicsPro Ltd. (http://Www.georadar.com.ua), engaged in geophysical research. The company resumes its activities after returning from Africa. I do not have skills in this work, only I study it. I ask you for help: I ​​conducted a survey using ground-based radar - Akula 9000 C + FLL 390. I also suspect that the cable is damaged. Vertical bands appear on radarograms, their origin is unknown to me. Using GPRSoft® PRO, the data was processed. But since I do not know how to correctly do this and interpret the data, I doubt the results. Created a 3D model.
And yet I can not recognize the geological layers and engineering communications.
Can you view my files and help me with the interpretation? There are a lot of hyperbole, but I do not understand - this is the level of groundwater, engineering communications or fragments of stones on the ground.

I really hope for your advice and help.

Dear jovtyu,
can you post the original gsf file without processing, there is not much that we can do with the image.

Dear danne,
Thanks for the quick response and help. I can not attach the gsf file. I get an error all the time
As I understood experimentally, do not download files whose size exceeds 1 mb, and my file takes 3 mb

All the same I was able to add a file

Dear jovtyu,
I have taken a look at your file and it seems to be that the offset setting is wrong and antenna is used in contact with the ground, which for the FLB390 is not a good idea.
Best regards,

Dear danne,
I used various offset settings: 0, 13, 19, etc. The antenna had no contact with the ground. Was at a distance of about 20 - 30 cm from the surface of the earth.
Thanks for the help!
Best regards,

Did you manage to solve this?
Regards,
