Abstract
A fiber-optic system for microwave angle of arrival measurements is demonstrated in an anechoic chamber for the first time. The system consists of a four-channel optical downconverter capable of processing received signals from 2-18 GHz. Direction resolution is determined by the antenna spacing, and at 10 GHz is spatially better than 0.1.
