Sampling rate comparison for a source reconstruction problem with Noise Added measurement data

In this article, a source reconstruction problem with four point sources is studied. The electric field data is used to reconstruct the sources. The field sampling is made with seven different sampling periods. Noise is added to the sampled field. The reconstructed field on the measurement surface and the reconstructed field with respect to distance are calculated to measure the performance of each sampling rate. In addition, the reconstructed currents are compared to the actual currents. The entries of the moments matrix are calculated with a semi-analytical procedure. This semi-analytical procedure has been recently reported by the author. The method of moments equation is solved using the least square QR method.
