摘要
A method for calibrating a phased array antenna comprises performing initial measurements of array antenna elements to ensure that calibration measurements are within the linear dynamic range of receive elements contained within the array. The method includes deriving calibration coefficients from a direct measurement of a forced out of phase condition and detection of deep nulls through adjustment of amplitude and phase settings over a range of frequencies of interest.
