I have obtained data from experimental detection using VNA. The data consists of 10 rows, which each rows consists of 22 a-scan points. I have successfully created a-scan and b-scan plots, but I can't figure out how to make c-scan. I've tried to use surfc(matrix), but because the matrix used is matrix b-scan, then the result is like in the picture.

What sort of visualization would you like? A surface? How about an image? What would you like each dimension/axis of the visualization to represent? Can you attach the data in a .mat file?

Thank you for commenting on my question
I want to make surface and visualization like the image below. x and y represent the position, and z represent the peaks of the signal received. What mat file did you ask?

Sorry, I'm not familiar with ground penetrating radar images. What do the x and y position axes mean? Is your a scan value the x value and b scan value the y value, and c scan value the intensity? If so, are the a and b (x and y) uniformly spaces? Or not spaced uniformly? If not, see my attached scatteredInterpolant() demo.

a-scan basicly, scanning in x axes, where you get data from x axes and the signal received. B-Scan is set of A-scan data in x axes, where you get the signal received. C-Scan is set of B-Scan (x axes and Y axes), where you also get the signal received from full area.

Hi, How did you create B-scan, I am struggling with it.

Hi, Could I ask you some help crreating A-Scan and B-Scan
I took S21 from VNA then applying Zero Padding and complex conjugate, and finally IDFT, but I havent obtain a parabolic in results.
Plz help me to solve this problem or if you dont mind send me the procedure you have done succesfully on my e-mail: bashar.wannos92@gmail.com
