Abstract
A calibration system for AESAs induces the AESA to produce a far field radiation pattern while near field measurements are taken; an initial calibration is produced, and complex aperture holograms are calculated. Based on the complex holograms, phase and amplitude error maps are computed. T/R module amplitude and phase are then adjusted to compensate for the error map. The system evaluates the refined far field radiation pattern to iteratively recompute complex aperture excitations to realize adequate far field performance and new hologram error maps until a desired level of precision is reached.
