A directivity comparison between hemispherical and planar arrays

Dan Li, Zhenghe Feng

Open publisher page 3 citations

Abstract

Hemispherical arrays are charming in receiving and processing multiple signals with wide space distributions, especially in integrated navigation systems. In this paper the directivity of a hemispherical array is compared with several kinds of planar array. It shows that the hemispherical array has an attractive scanning directivity performance through the hemi-space above earth plane, especially with small numbers of elements. The effect of element pattern, element number and minimal element spacing is discussed.
