[[NeoScan]] systems can be used as an essential tool for characterization, test and evaluation of antennas and phased array systems. It is well-established fact that once you have an accurate estimate of the aperture fields, you can compute the far field radiation patterns of an antenna with reasonable accuracy. This fact is based on the equivalence principle and the Huygens theory in electromagnetics.
