Directivity Patterns of a 5-Element Linear Super-Directive Array Using Pritchard and Bryn Shading Methods.

Abstract

From the limited number of results, it is concluded that Pritchard's method results in low minor lobe levels without broadening the main lobe unduly. Bryn's method results in narrow main lobes, but at the price of higher minor lobe levels, or an increased number of minor lobes. Also, the method of shading is sensitive to the noise ratio (system noise to ambient noise). A change in either or both may produce a substantial change in the directivity pattern. It is not intended that these results should be extrapolated to longer arrays; each array needs to be studied individually. (Author)
