- Abstract
- A technique has been developed for accurately solving the problem of geometric-optical synthesis of a bifocal system of two flat reflect arrays, based on the sequential determination of the distribution of the eikonal introduced by different sections of the arrays, with its assignment at the initial section of one of the arrays, while the introduced eikonal at the initial section of the other array is found as a result of synthesis of the output flat front for the central position of the feed. The technique ensures the continuity of functions describing the distributions of introduced eikonals, as well as their first and second derivatives (along one coordinate) at the boundaries of sections. The dependence of the value of the mean square eikonal aberration at the system output on the arrays parameters has been studied. As an example of the application of the developed technique, the bifocal systems for visual angles of 40° and 65° were synthesized and optimized. A study of the radiation characteristics of an antenna based on synthesized and optimized bifocal systems was carried out.
