ABSTRACT:
A method for obtaining excitation errors of elements in an array antenna increases the element unit cell area in the aperture plane by reducing the size of the fundamental period in spectrum space. An element unit cell in the aperture plane is increased by appropriately selecting rows of elements to establish row sets. A polarity of near field measurements are made with the phase shift applied to the elements of one row set for each measurement and the spectrum for each row set is determined from the data of the plurality of measurements. This spectra is then utilized to determine the element excitation coefficients.
