Abstract
A calibration method, applicable to element-level digital arrays operating in the receive mode, which utilizes the individual element plane wave spectra obtained from a single planar near-field scan. The method generates highly accurate near-field measurement derived amplitude and phase calibration of both large and small digital arrays as a function of array scan. The present disclosure provides digital array calibration methods and their potential uses in satellites and directional arrays.
