There are numbers of mode provided in SIR3000 screen (Terrasirch, geology scan, utility scan, concrete scan). Please have a look on attached profiles where I have tried Geology scan (Top section ) as well as TerraSirch (bottom section). In TerraSirch mode there is option to control gain which I didn't fine in Geology scan. Bottom section looks better in amplitude varriation but penetration depth is limited.
Please advice for further acquisition.
Hello Pranjal,
I have used Geology scan for cavity detection studies, it worked well in our study site. You should also take 3D data to get more information about the dimension of the cavity.
All the best

Thanks
Yeah! I acquired profiles in grid system for 3D presentation of result.
If you have a look on attached radargrams; In geology scan, data penetration was looking better but the reflectivity varriation was not prominent whereas in TerraSirch mode, variation was quite good but the penetration depth was limited.
Could you please share some papers or references related to this?
I think manual set up using TerraSirch mode is always better for the cavity search.
