How to do image reconstruction from array data? i have 15 set of data which is the s-parameter, consist of 2 column (1001x2) each set. The first column is frequency and the second column is magnitude in dB. I have transform the magnitude from (dB) into value and frequency into time. But i have no idea how to transform these 15 sets of data into an image by using Matlab. Can anybody help me?
You will not be able to reconstruct the image without the phase information.  The frequency magnitudes alone are not sufficient.
