Abstract
This article examines the parallel calculation of radiation patterns (RPs) for active phased and multi-beam antenna arrays (AA), assessing the computational complexity of typical problems. This article is the first in a two-part series devoted to the parallel calculation of AA RPs. The introduction presents examples of large-aperture AA. The first section of the article presents formulas for calculating AA RPs and discusses various methods for specifying the coordinates of the studied angular directions in which the RPs values are calculated, as well as the corresponding methods for displaying RPs plots. The second section describes methods for calculating the RP of a radiator operating within the AA aperture, taking into account of the mutual influence of adjacent radiators. And, the third section examines typical computational problems solved when calculating AA RPs. The computational complexity of these problems is estimated.
