Planar antenna array and phase comparison - mono pulse radar system

摘要

Planar antenna array which, in the form of a receiving antenna (10; 40) is formed, with:a plurality of antenna elements (24; 44), which are arranged in a matrix structure, which is composed of columns and rows;a feed device, which feed lines (26a, 26b; 46) for supplying electrical power from the antenna elements;a switching device (28a, 28b; 48a, 48b) for opening or closing of the feed lines of the feed device, which, with the right and left columns of antenna elements, which are connected in a region at the right-hand end or in a region at the left-hand end of the matrix structure are located; anda terminal (a, b) for the switching device (28a, 28b; 48a, 48b) for feeding in of the switching signals, in order to the switching device for the alternate opening or closing of the feed lines to cause in such a way that the right and left columns of antenna elements, which in the field at the right-hand end or in the field at the left-hand end of the matrix structure are located, are alternatingly activated,..
