An iterative transform technique for solution of large, finite phased array problems

Abstract

DEVELOPMENT OF THE ITERATIVE TECHNIQUE, For convenience w e consider an N element linear array along the z-axis, nith constant element spaang equal t o d, . the i terat ive technique may easily be extended t o planar arrays. Under the minimum scattering approximation, the voltage, vtn), is the discrete convolution of the sum of the antema mutual impedance sequence, fa(nd ), and the feed network mutual impedance sequence, Zftndr, with the current sequence, i(nL The limits on the cznvolutien summation may be extended to f m such that
