An Evaluation of Shore-Based Radio Direction Finding.

Abstract

This report describes an evaluation of Radio Direction Finding (RDF) techniques for shore-based position location performed by the Transportation Systems Center (TSC). The evaluation consisted of the following three phases: (1) A preliminary survey to identify and classify available direction-finding techniques which could meet Coast Guard requirements; (2) An analytical modeling and error analysis of the equipment types identified in (1); and (3) Field testing and demonstration of representative equipment. Major system characteristics considered in the study were: (1) Operational utility of such a system; (2) Cost to implement the system throughout the USCG; (3) Operational impact on the group level - manning and maintenance; (4) Compatibility with existing land lines and VHF-FM remoting capability; (5) Operation in a VHF-FM maritime mobile band; (6) Location of the DF antenna; (7) Ability to home on both voice and EPIRB; and (8) Interference effects.
