Abstract:

The purpose of this study was to analyze techniques for combining outputs from a multibeam antenna, such as a Butler Matrix or a Rotman Lens, in order to implement a direction of arrival DOA capability. Emphasis was placed on determining the accuracy of several DOA techniques as a function of signal- to-noise SN ratio with a common antenna aperture. The impact of cross polarization and sidelobes on DOA accuracy was also considered. Study results will assist in defining antenna types for ESM systems and their performance capabilities.
