Paper Abstract

An improved optical technique for electrical phase measurement has been developed at the Naval Research Laboratory under ARPA sponsorship. The approach has been demonstrated in an rf interferometer application and its performance evaluated under condition of direct rf injection and free-space irradiation. Test results indicate high-accuracy angle of arrival and low probability of ambiguity was achieved. This paper describes the phase measurement concept, implementation into the NRL Precision Direction Finding Receiver brassboard unit, calibration techniques, automated test software, and measurement results.
