Sensor configuration in polarized antenna arrays

Abstract

Single- and dual-polarized array configurations are often used in imaging and radar applications. In this paper, spatio-polarimetric correlation are used as a framework to evaluate the direction finding performance of dierent receiver configurations employing double-feed dual-polarized array as well as arrays of single-feed single-polarized elements. The spatio-polarimetric correlation coecients are derived for several array reconfigurations and used to provide a configuration-based performance comparison based on spatial resolution and grating lobes.
