Phased array tool box for Full Matrix Capture FMC

Hi, I was wondering about the capability of Phased Array Tool box for acquireing the data in FMC format. In FMC data acqusition method, an element shots while the other elements are lisening and this procedure is repeated untill all elements are shoted. The out put will be a huge matrix (e.g., n*n for an array of n elements).
Any experince with this method?

Hi Mohsen,
Could you be more specific on this?
If you are asking whether the Phased Array System Toolbox is capable of simulating such a process, then the answer is yes. You can certainly fire successively on the transmitter side by zeroing out other elements via weights at the time of transmission and then receive using the full array. Note that at this point the toolbox assumes plane wave in the simulation.
If you are asking whether the can acquire such data, as long as it can be imported into MATLAB, Phased Array System Toolbox should be able to work with it.

Hi Mohsen,
If you want to connect directly to the hardware, there is a Data Acquisition Toolbox which you can use to get data into MATLAB. But I don't have a lot of experience with that so I can't offer any useful advice there.
I personally haven't worked on any nondestructive testing project so I don't exactly what needs to be modeled in such a case. Do you have a overview reference I can read about? I'm definitely interested.
From your description, I do think you may need to develop a model representing the steel pipe (you may have one already). The only other thing I can think of that may get into the way is that most simulation in the toolbox assumes far field propagation, or plane wave to be more specific. I would be interested to know if it doesn't sever your purpose and if so, what kind of model you would like to use.
Thanks.
