Over-the-Air Phased Array Calibration Based on the SPGD Algorithm

Phase errors of phased array antenna (PAA) can cause pattern distortion. This letter presents an over-the-air (OTA) phased array calibration method by an iterative stochastic parallel gradient descent (SPGD) algorithm. During the measurement, all the phased array elements are excited simultaneously,...
