Method for generation of sum- and difference antenna patterns with low sidelobes for planar antenna arrays

摘要

The invention relates to a method for the generation of sum and difference antenna patterns with low sidelobes for planar antenna arrays. In order to generate these diagrams with minimal effort, the following measures are proposed according to the invention: for the individual antenna elements i, i = 1, 2 ... N, is the azimuth plane and / or the elevation plane (each) of i predetermined constituted ratio d _i / f _i and quantized with d _i is equal to one for the individual antenna elements difference lobe review, w _i is equal to an amplitude rating given for the individual antenna elements i; the antenna elements with the same quantized ratio d _i / f _i for azimuth and / or elevation are N ', respectively combined to form a sub-group j, j = 1, 2 ...; the generation of the sum and difference antenna patterns is carried out on the basis of the subgroups j formed.
