Abstract
In some example implementations, there may be provided methods for beamforming calibration of active electronically steered arrays (AESA). In some implementations, one or more adders may generate a phase offset by adding phase calibration data from non-volatile memory and phase command data from static memory, and/or generate a gain offset by adding gain calibration data from the non-volatile memory and gain command data from the static memory. Further, a phase-shift circuit can modify, based on the phase offset, a phase of a first output signal, and an amplitude gain circuit can modify, based on the gain offset, an amplitude of the first output signal. In accordance with these implementations, the modified phase of the first output signal and the modified amplitude of the first output signal are provided to enable pre-calibration of the first output signal and/or a first antenna. Related systems, methods, and articles of manufacture are also described.
