Ground Penetrating Radar (GPR) B-Scan Collection (FDTD Animation) [Georadar]

[@hellotianhong]

Wow, I'm very interested in this animation. I have used gprmax and paraview to achieve electromagnetic wave transmission and reception, but I don't know how to achieve electromagnetic wave and B-scan to play simultaneously, your animation is very good. Can I analyze the implementation methods and code?

Salaam, if you have E fields in X, Y already (of course it should be at each time steps) then for a given x,y position you have to plot the time-domain signal with respect to time to get the A-scan. Then when you repeat this for different x positions at the same y location (e.g. [x1,y0], [x2,y0], ...,[xn,y0]) Then it will give you the B-scan. You are almost there actually. Thanks

It was an interesting video, thank you. Is it possible to get the implementation code of this structure from you, please? In fact, the code part of the migration algorithm

[@meyavuz]

thanks, but the video is 10 years old, I don't have the code at this moment.

[@meyavuz]

Hi, thanks... IF you already have the 2D simulation data, then you can use imagesc or pcolor to plot the B-scan data as well. Actually, it is very straightforward. What I did is to allocate an array with zeros first, then fill it up appropriately as the A-scan data is recorded at the antenna location. I hope this helps.

Hello can you help me with the B scan animation ? Thanks

Hi.. Can I use your video for my channels, please?

[@meyavuz]

Sure, go ahead. I would appreciate if you can link to my video (or channel) in the description of your videos. Thanks

@@meyavuz Thanks very Much.

Hi, for my project i am asked to simulatre a through wall human detection environment using uwb radar. which software can i ues for simulationg the environmnent.

[@meyavuz]

this was in matlab - try gprmax on the google

[@mohamedmetwally5210]

Hello, this really was a job well done for practical purposes. I have achieved the E-Fields in X and Y directions. But I have no clue how to combine this data to get A-Scan or B-Scan. Would you mind sharing the code you used for cross examination and for learning purposes please?

Hi guys I have a question.I am researching about GPRs (ground penetrating radar). I want to detect there is a metal or not under the surface by generating 2D map of the subsurface.I am collecting datas by scanning the surface by taking measurements moving in one direction and storing them in an exceI file but unfortunately I dont have any idea about how to produce B-scan or A-scan. Could you help me about this?

[@neilnazir6037]

hi Did you get successful in getting a B scan? I am also working on GPR and I am looking to generate B scan. If you have any MATLAB code then it would be helpful.

[@meyavuz]

Sorry for the late reply. You just need to collect the data in different location and plot them as shown here

hi, the 2d simulation with the bscan is nicely plotted.iam also working on fdtd with matlab.iam able to do 2d animation,can you help me with the commands that has to be used for plotting bscan
