Analysis of Methods for Reconstructing the Amplitude-phase Distribution of Antennas Measured in near Radiated Field Zone

The paper discusses a technique for diagnosing antenna arrays, including phased array (PAR) and active phased array (APAR), as well as feeds of multi-beam hybrid-reflector antennas, carried out at the stages of development and testing. The proposed method, based on measurements in the near-field zone of the antenna, could be an effective diagnostic tool at the stages of development and testing.
