A Comparison of Radio Direction Finding Systems
Abstract
Small and large aperture rdf systems (both existing and proposed), and limited space distributions of narrow aperture rdf systems are compared in terms of the bearing error which arises when a desired and an undesired signal of the same frequency but having arbitrary relative amplitude, arbitrary time phase difference, and arbitrary relative directions of arrival are incident upon each of the several systems. The effect of increasing array diameter upon the bearing error of large aperture systems and distributions of small aperture systems is also considered. The comparative results are shown in the form of bearing error curves, photographs of simulated system performance and as a tabulation of average absolute bearing error for each system. A discussion of the practical problems involved in the realization of some of the proposed systems is included and significant conclusions are stated.
