OPTIMIZATION OF PERFORMANCE INDICES IN DISCRETE ARRAY SYSTEMS.
Abstract
A basic theorem useful for the optimization of the performance indices of arbitrary antenna arrays is first reviewed. It is then applied to a general, three-dimensional array. In particular, it is specialized to determine the maximum obtainable directive gain and the main-beam radiation efficiency for circular and elliptical arrays. The gain optimization principle is also extended to arrays responding to quasi-monochromatic periodic signals and to arrays which are subject to random errors in excitation amplitudes and phases and in element positions. When the performance index of interest is the output signal-to-noise power ratio, consideration must be given to the power spectral densities of both the signal and the noise, the noise spatial distribution, the antenna space-frequency response function, the system internal noise, and the transfer function of the linear processor. The procedure for the maximization of the output signal-to-noise power ratio of an array of an arbitrary geometrical configuration when there are random variations in the design parameters is also reviewed.
